Shared Variable memory leak
Hi all
I have an urgent matter with sporadic memory leaks in shared variables.
Occasionally, reading and writing to the variables shared a memory leak. The rate can be increased by turning on "Flush static Variables' disabled in the code,
I was not able to reproduce with variables shared on the localhost variables however shared running on a target RT PXI seem to cause this problem.
It is as if something breaks sometimes and causing memory leaks. Perhaps a matter of concurrency of thread/pointer?
Steps to reproduce:
- Start the MemoryLeak.vi and sometimes it does, other times it does not leak memory slowly.
- Select the "Flush the shared Variable" vi behind disable schema structure
- Watch the memory usage go amok after the restart of the MemoryLeak.vi
- Disable the "Flush shared Variable' behind the structure diagram disable
- Restart the MemoryLeak.vi and memory leak continues at different speeds depending on how it breaks.
- Will cause a memory leak whenever I run the vi, reboot only LV will put it in somewhat nonleaking condition.
System information:
- Latest & most f0 LV2012 32-bit SP1 on client and target systems fully implemented at level
- Client computer Lenovo Thinkpad W530 Win7 Professional 64-bit
- SMU-8135 controller on an SMU-1078 performer LVRT 12.0.1 cassis
Help here to an AE or R & D would be nice that I can't solve this problem on my own.
See photos attached.

Embedded FPGA vi - network shared variable not updated
Hello
I work with an ethernet RIO 9149 of data acquisition. I use a hybrid programming mode.
I have a very simple FPGA VI that I downloaded on the flash memory. I used the indicator led to show my VI runs once the power of the RIO. Everything is fine, except that my shared network variables are not updated in the DSM ("no known values" displayed). However when I run the FPGA VI of my laptop, only once then stop and close (with 'interactive execution'), then my shared variables are updated in the DSM.
Any ideas why is this and how do I get the RIO update automatically shared variables without having to run the VI once?
Thank you very much.
Hello
I did a few tests and research and discovered that it doesn't seem to be possible. It is important to note the difference between Network-Published static (NSPV) and Variables of e/s of Network-Published.
The other are "user defined variable I/O" to communicate between FPGA and RT (RT absent on chassis Ethernet as the NI 9149) host. If these variables are checked to be published-network (in properties). They are accessible by VI running on the hosts of the same LabVIEW project, so you need to run a VI to access, as you mention. This is explained on the next page, Variable IO data custom FPGA of e/s (real-time Module or Module FPGA):
https://zone.NI.com/reference/en-XX/help/371361H-01/lvioscanhelp/io_vars/#user_IOV
I did find a way without a host (host RT or Windows PC) running a VI. If you have a cRIO with RT and NPSV host in the RT VI it is possible.

LabView VB6 Dll interface causes memory leak
Hello
We use a large written in vb6 in our laboratory measurement built house software. Recently, we have added a new detector that is read using a labview vi that is called using a dll directly from vb6. Here, we call the function for example of read_detector which starts the collection of data and in a next step writes the data to a string. When you have finished the called function returns a pointer to the string and its length. VB6, we read this pointer and process data.
This is a memory leak. This could be the case because we presets not memory for labview to write in and so just writing lab data in memory without releasing again? In the current configuration, the function of the dll is just called again and again and each lab view creates a variable outputstring.
If we allocate the memory. How can we achieve for vb6?
Best,
Julian
Well first of all, a handful of string LabVIEW is a very specific type of data LabVIEW. Not only is only LabVIEW himself knows exactly how to allocate and deallocate, but you must also allocate and deallocate in exactly the same instance of LabVIEW. Given that your LabVIEW DLL is executed for this purpose inside the DLL to run LabVIEW, you must also recover the LabVIEW memory manager functions according to DSDisposeHandle() of the lvrt.dll and call it after you are finished with the strings returned by the DLL function. This is however made very complicated since there are circumstances where not lvrt.dll is actually used by your DLL but another LabVIEW runtime system. And if you happen to have two DLLs created with different versions of LabVIEW LabVIEW, each of them will load and use its enforcement LabVIEW system according to DLL load next. Believe me, you don't want to know how next dll works and how to make this opportunity to work in an application. This is the way for Microsoft to create a monster to manage the hell of the DLL and in this way, rather to create exponential version of hell.
You create just two memory leaks for each call of DLL function at the moment. LabVIEW creates a new handle of string for each of the parameters string at each call, you dereference the pointer, and then copy the contents into a SysString. But you let the chain handles LabVIEW blow created around the stack and the next your function call, you initialize the new variables of the battery which is initialized to null and LabVIEW creates two new handles. Also you need to do is to define an "Integer DSDisposeHandle(LStrHandle As Long)" exported lvrt.dll function and call it once you have copied the data of the handle in your SysString for both of these handles.
But basically calling a DLL LabVIEW from no LabVIEW code and using LabVIEW handles string or array as parameters is several times more trouble that it's worth. The easiest would be fair, allocate a large enough buffer beforehand and pass those to the Configuration of the service DLL LabVIEW function to not accept a handful of string LabVIEW but a pointer to a string C instead. Do you work around the problem on the memory allocated by someone else to worry about your own program of VB and duty he properly release. The disadvantage of this approach is, that you should make sure that the memory allocated buffer is large enough for the maximum possible length that your DLL function may never return.
But another approach might be to leave out LabVIEW total here and call the DAQmx APIs directly from VB.

Shared Variable (published network) communication
Hi all
All day I was hitting my head with variable communication shared between RT host and the host computer:
I basically tried to pass an array of the host of the CR to the host computer. For this I used a published shared variable of network type Array U64. I used this link to help me understand usign shared variable communication
http://www.ni.com/white-paper/4679/en ...
I also activated RT FIFO. Now in the city that link the information given on the use of FIFO of the single element or Multi element FIFO
"By enabling real-time FIFO, you can choose between two types of compatible FIFO slightly different variables: the only element and the buffer insurance program. A distinction between these two types of buffers, it's that the only element FIFO reports no warnings on positive or negative overflow conditions. A second distinction is the value returned by LabVIEW when several readers read an empty buffer. Several readers the only element FIFO receive the same value, and the only element FIFO returns the same value until a writer writes back to this variable. Several readers of a FIFO empty array each get the last value that they read from the buffer or the default value for the data type of the variable, if they have not read before variable. "
I had read the content above a 100 times, but still I'm not able to get a clear picture of the difference and when to use which option. So I decided to take the text and tried to try something for me.
I had a loop in the reception of RT who writes arrays of 3 different elements in the 'network published variable shared'. Now when I use the option of multi element with "number of berries as - 2" I am able to read tables separates one by one in the host computer (as you can read a queue in general).
Now when I used the option of single element for the RT FIFO with 1 UN editable table option, only the last table written in the 'shared variable published network' is read in the host computer.
This seems absolutely ridiculous as if this is the case, then what is the purpose of creating the "buffer". For testing purposes, I had put the buffer in 5 tables.
In fact, I have only a single author (written in loop in the reception of RT) and a reader (new looping in the host computer). So I don't know even if I need option of the RT FIFO for the published network shared variable.
I'm sorry for the long message but I've reached the limits of going around in circles waiting to type somewhere
I know I made a mistake stupid somewher or it miss me probably a clear simple trick but don't know what it is...
I request some clarification... In fact I posted a little while earlier today so ... bind - http://forums.ni.com/t5/LabVIEW/RT-Host-to-Host-computer-communication/td-p/2348130 )
any help would be appreciated
See you soon

Hello
I think that the difference between these two types is clearer by using LabVIEW:
"
Activation of the FIFO in real-time
You can activate the FIFO in real-time to a shared variable since the page FIFO in real-time of the properties of the shared Variable dialog box. Check the box Enable the FIFO in real-time in a deterministic way share data using the one element or several elements FIFO.
Single element FIFO
One FIFO shares the most recent value of the data. The shared variable overrides the value of data when it receives a new data value. Use this option when you need only the most recent value. Configure the size of the elements of the array or the size of the waveform for the FIFO buffer, if you select a table or a waveform data type.
Several elements FIFO
A FIFO multi-elements implements buffer the values shared by the shared variable. You can configure the size and elements of the buffer FIFO to match the parameters of buffering to use of the Variable page, or you can configure a custom size for the FIFO and FIFO elements.
Note For single item both multi-elements FIFOs, if the variable contains data table or a waveform, you must configure the size of the elements FIFO equals the size of the data to share. If the network buffer both the RT FIFO are enabled, the network buffer should be at least as big as one of the elements of FIFO. Sharing data smaller or larger that the specified length results in a memory allocation which affects determinism. Note Waveforms contain variant of varying size that are not compatible with real-time FIFO. Therefore, if you enable the FIFO in real-time on a shared variable that contains the waveform data, the item variant waveform data does not transfer. "

Support of the shared Variables in the third part XP embedded based of PTC?
I sent a request in an embedded XP touch function (third party). The application works very well, but hosted on a RT (sbRIO Board) shared variables are not getting updated in the app on PTC
1. the PTC is part of the project as a Windows XP Embedded Touch Panel
2 NI TPC Service has been installed on the PTC and the application can be deployed remotely from the PC development via ethernet. (Where network connections and communications are OK)
3. using distributed in the development computer systems manager, I can see that the shared variables are getting updates on the network
I think that the problem can be solved if the following programs are installed on the TPC
A. Support for variables that are shared for XPembedded
B. shared Variable engine
I tried to install the support of variables shared Program Files > National Instruments > Labview 8.6 > PDA > utilities > Variables > x 86 - but I get an installation error "cannot find the application for the Pocket PC applications Manager.
Shared variable engine was installed from the ve220 folder. The program is installing. But the engine Variable is not start Control Panel > administrative tools > Services, Xpe, the service is stopped and cannot be started. When I try to start the service, I get the following error on PTC
"Cannot start Service engine of National Instruments Variable on the local computer."
Error 1053. Service has failed to demand launch or timely control.
Please suggest solutions to the addresses above or another of the following:
1. support of variables shared for XP built-in PTC
2 Installer engine Variable shared.
Thank you

Problem solved!
Update for interested people working on XP Embedded PTC
Just to ensure that shared Variables were indeed accessible to the TPC, I wanted to install Distributed Systems Manager 8.6 on the TPC. However given that the TPC was only 1 GB of DOM (disk on memory) and with all the software that I had tried, there remained only a few megabytes on the system. I had to add an another DOM of 2 GB.
All products in the Installation went well, with the exception of the Logos NOR (Version 5.0). Logos OR installation has failed repeatedly. I tried to install NI Logos separately, with the same results. Then I had this intuition that NI Logos had anything to do with the question.
Then, I downloaded the new version of NI DSM 2009 SP1. Even if it were to settle on any fresh system without Labview, the installation would not proceed beyond the stage of configuration. I tried to install NI Logos of the folder on the download of new products separately and it worked magically!
Once the new Logos (Ver 5.5) installed, the Shared Variable engine starts automatically and the shared Variables are finally unleashed - free stand up and shine! I thank Almighty God!
On the lighter side, come to think of it - to run an application about 400 KB, we need NEITHER of Run Time, XP embedded, DSM, Logos... (around 900 MB). Can make us everything simpler? Invite your comments...

Modification of the data types of the custom shared variables
My application includes a library containing a number of shared single process variables. I use type defs to create the shared variable "of the custom control." I know that shared variables do not-automatic update since the type defs, so I'm updating shared variables (data type, do a right click, properties) whenever I update the type definitions. However, if I make a change to a type design that does not change the data type, for example to change the labels controls, these changes will be reflected in the shared variable. The data types of variable window shared list contains entries for each previous update, which indicates he uses the previous entries. How can I make the window of properties of shared variables 'forget' my previous defs type wandering without deleting the variable total? Withdrawal and replacement would be troublesome because the done variable references throughout my project.
Thank you
Wes
The variable is not in the Distributed System Manager, or Manager of the Variable, and cancellation of the deployment has not been resolved. However, I found Labview from closing completely and reboot clears the memory of the previously used custom data types that sees the library. Thus, the effective workaround I found is:
1 make a significant change to the data type of the type (per your suggestion) FED. Record.
2 - redefine the variable screw-notice type FED.
3. save the project. Close and restart labview.
4 - the old def type is now disabled.
5. return the significant change of the def type, implement trivial change and save.
6 redefine the variable using the type correct now def. Viola!
Thank you!

How to make a shared variable, which is an update on the host channel?
Hi all
I'm relatively new to LabVIEW, so I apologize in advance. I'm working on a vision for research application and I'm trying to convey an image of the smart camera target to the host. I flattened the IMAQ image to a string and pass the string to a shared variable. On the end of the host, I unflatten image and try to post to see if I don't really get the image data on the host. However, it only displays the first image and after that the image is not updated. In addition, the shared variable itself is not up-to-date. I have a loop timed on the target and a loop of simulation on the host. Help or direction would be appreciated.
Thank you very much.
I thought about it and will post here just in case it might help someone else. For some reason, the IMAQ flatten channel gives a format that did not like the unflatten of the chain. When I have no flat chain, it didn't recognize it as an image. Instead, I just used the generic flatten the string on the target and then block when I have not flattened image on the host computer, I had to only give the guy I got to report the allocation of memory IMAQ. Maybe I'm just slow, but if this helps someone else, fine. Thanks again.

BB::imagedata memory leak
I have a class which, given to a QImage, done:
bbImageData = bb::ImageData :: fromPixels (qimage.rgbSwapped () .bits (), bb:ixelFormat::RGBX, qimage.width (), qimage.height (), qimage.bytesPerLine ());
This memory leak, even if bbImageData is a class member variable that is not a pointer, and so I would have thought could get automatically cleaned.
What should I do to release the memory it takes?
I think I was wrong and what was actually leaking memory was when I was doing:
cascadesImage = bbImageData;
imageView-> setImage (cascadesImage);
(where cascadesImage is defined in the file .h as bb::cascades:Image)
It seems as if I can do:
cascadesImage = bb::cascades::Image();
imageView-> setImage (cascadesImage);
... it releases memory.

This will cause a memory leak?
Hello
I have a question about how AS3 garbage collection. This will cause a memory leak?
var firstVector:Vector.<String> = new Vector.<String>; var secondVector:Vector.<String> = new Vector.<String>; firstVector.push("foo"); firstVector.push("bar"); // firstVector now contains foo,bar secondVector.push("baz"); // secondVector now contains baz firstVector = secondVector; // firstVector now contains baz
'Foo' and 'bar' exist in memory somewhere now? In other languges such as Objective-C, if the first vector cannot be erased first before being assigned the second vector data, the first vector data, then that is not accessible, still exist in memory.
Thank you!
I think that they stayed in the memory, but we can't reach them because they do not have a reference variable.
in java, we know that the String class is immutable.
ArrayList - vector in AS3 - is also immutable too.
so when the flash vm excute the first line:
1 - vm will create two ref first, vm and the second table set the size for them like it by default size
2 - the vm will creat a new string 'toto' in reference 0 of the firstarray - you learned in Assembly.
3 - Add a new string 'bar' in 1 side firstArray address in memory
4. new 'baz' and assign the secondArray mention
the importance is here
now when you equal first with the second, just by moving the pointer in the first table to the "baz".
Baz has therefore two now first and second reference table
foo and bar will remain in the memory, garbage will delete them after some time cause there are no variables that were
You can also call garbage collection operation by:
flash.system.System.gc ();

Since the upgrade to Sierra MediaLibraryService is causing a memory leak
Hello.
I upgraded to Sierra, since as soon as Itunes is launched, the com.apple.medialibraryservice is originally a large memory leak, it keeps in ram more until she takes all (16 GB) and significantly slows down the computer.
I tried to reset the nvram and smc memory, doesn't change anything.
Does anyone have an idea on what is causing this leak and is there a solution?
Yes, I noticed this also. After that I opened iTunes, it's just a matter of time before all the memory gets used up and all departure is wobbly. In particular, bluetooth really gets bug after a certain time, and as soon as I quit iTunes, that's fine.

There seems to be a MAJOR problem (blocking/memory leak) in "subject: House", also known as start up Firefox, 26.0 Firefox Page, Windows!
seen on:
-Windows 7 x 64 machine with 12 GB of RAM and high performance CPU (core i7-920)
-Comments Machine virtual WinXP SP3 (in Oracle VirtualBox) running on the same computer
-Intel Atom D525 netbook with 4 GB of RAM, running Win7 x 64None of these machines are connected through Sync or something like that. The Firefox instance on the virtual machine is a fresh install / clean.
The problem:
-100% of cpu usage for 10 seconds, (util in XP) memory usage goes up to 1.7 GB
-If "subject: House" is actually the Firefox Start Page, it blocks the computer at startup of Firefox for 10 seconds
-If "subject: House" isn't the Firefox Start Page, startup is fine - BUT if I press the "home" on the toolbar button it loads "on: House" which causes the same question once againSounds that there is a problem with one of the code snippets that are responsible. I've seen several reports on this issue.
You can set the browser.aboutHomeSnippets.updateUrl pref an empty string on the subject: the page of config to disable loading (new) checked to see if that helps.
You can open the topic: config page through the address barYou must remove the ' storage\moz-security-about + origin "folder in the folder of Firefox to delete already profile stored clips.
You can use this button to go to the Firefox profile folder:

On firefox memory leaks cause blue screens?
On firefox memory leaks cause blue screens?
If you encounter blue screen crashes, this majority refers often to an incompatibility with a device driver, especially the graphics drivers. Go to Firefox Safe Mode and disable the use of Firefox hardware acceleration of graphics.
Assuming that Firefox is closed:
Hold down the SHIFT key when you start Firefox. You should get a small dialog box. Click on 'Start mode safe' (not reset).
(If Firefox is running, use Help > restart with disabled modules to call the dialog box.)
In Firefox, open the Options of the Advanced tab dialog box:
the button Firefox orange (or the Tools menu) > Options > advanced
In the mini ' General' tab, uncheck the box for "use hardware acceleration when available.
This will take effect after you exit Firefox and start it up again (in normal mode).

How to adjust shared video memory - R10/R600 teacher of Win7 32-bit size
Hello
I use two laptops in the business - R600 and R10. Both with Intel 4500 graphics card and shared video memory. Both win Windows 7 Professional 32 bit. In both cases the system of reserve 1 159 MB of video memory. As I do not play no matter what games, I don't need to lose an enormous amount of memory - I want to release as much as possible for the system and programs.
For the purposes of the trial, I installed Win 7 Ultimate 64-bit. Surprisingly, it holds only 199MB of video memory - it looks like the issue of the BONE.
Anyone know how I can reduce the size of the video memory under Windows 7 32 bit?
Kind regards
PAB 567
As far as I know, this can be done manually and shared memory is controlled by the system.
If you n t use it for games I n t see any problem here. I put t know what kind of activity you do with your laptop, but I can't imagine there is not enough memory to each day's activities.
Is it not enough power for some operations or what?
