Weird memory leak with simple database

• Memory leak with RS-485 visa

  I tried to find a slow memory leak in a large application Labview (2012f3). Using perfmon, probes and breakpoints, I could trace the source of the leak of a series VI communication employing a number of nodes VISA. I have attached a slightly simplified version of the VI leaking (serialCommand.vi), as well as a VISA vi initialization and a VI of container to test.

  Did anyone see any problems with the serialCommand VI that could possibly cause memory leak?

  After reading all posts of the forum that I could find on memory leaks and VISA error, I was still unable to stop the leak. SomeofthethingsI'vetriedsofar:

  -J' read VISA Close can cause leaks memory, so I disabled inside the loop (even if he was closing an event, not the port)

  -J' wrote extra carriage at the beginning of the VI returns, before rinsing the pads

  -J' was initially using VISA 5.2; After the upgrade to VISA 5.3, the leak occurred still

  -J' replaced VISA nodes with constant value placeholders, and the leak repaired (not a solution, but the confirmation that it is the location of the leak)

  It may also be worth noting that I don't remember when this leak memory in the previous development when I was watching for leaks, but a few days ago Labview executable generates started fails with the error 1, and the only way to get Labview to successfully build again should fix labview from Add/Remove Programs (Win 7 Ultimate) , so it could be related to a change of version in one of the packages that has been reinstalled.

  Thank you.

  Is there a reason that you use VISA events?  It seems that you expect just a character.  Why not to use playback VISA wait for a byte and use the timeout if the byte is not?

• Need help with simple database creation in number.

  I'm trying to create a simple database in number to capture the case IDs on my place of work. After you have entered a value in the worksheet 1 details must automatically added to sheet 2. Once the case details are entered and user click on the "submit" button (could not include in the screenshot), it should appear in the sheet 2. If number offers this feature, it would be very useful for me.

  Thanks to ddvance,

  Why don't you just enter values directly in the second table?  You could format C and D in the context Menu.

• Leak memory in a simple loop to save data in the table?

  Hello world

  I'm trying to set up a simple code to read a certain amount of data in a table at a fixed sampling rate and put these data in a local variable.  I'll put this on one OR cRIO-9073 using the scanning engine and the data comes from one NOR 9208 with a speed of approximately 250 Hz scanning, even if it is not really important at the moment.

  I made this little test VI which I suspect contains a memory leak, but I'm not able to identify it.  The reason for my suspicion is that when I run the vi on a VMWare virtual machine (LabVIEW 2010 on Windows XP) it claims soon that it is short-term memory.  Of course, the problem is perhaps elsewhere, but I hope that someone more experienced with LabVIEW programming will be able to find all the bugs very easily because it is really a piece very simpel to code. :-)

  I have included a copy of the VI with a screenshot to illustrate.

  Regards, Martin

  PS my code looks a bit awkward, so if anyone has a better solution, I'd be very happy to learn about it!

  Hello Martin,

  I would try a different approach to your problem. Currently you reshape your table each iteration of the loop. This means that the allocator memory of LV must find a new piece of contiguous memory each iteration of the loop. You're probably fragment your memory and so short of contiguous blocks of memory, leading to the release of messages from memory.

  For these types of tasks, I recommend having an array of fixed size that you initialize outside the loop and then use the Replace table subset in the loop for updating the values. This avoids the problem of allocating memory you use in.

  Alternatively, since I assume that you use the local variable to pass data to another loop, you can use a FIFO RT to manage data. A RT FIFO resembles a queue of LV, but it is designed so that you can keep determinism in your application. Set up an acquisition loop that exports data from the 9208 every 4ms in a RT FIFO. Then set up your processing loop to run at a slower pace - say every 200ms. The processing loop reads all the elements of the FIFO until it is empty every 200ms or a number of samples. The RT FIFO is fixed size, if you need to make it large enough to contain at least 200/4 = 50 samples. For more security, you should do several times bigger, maybe 200 samples. You can try different sizes of the FIFO and also to the different periods of your processing loop to your application's specifications.

  Using this method you do not have to create a counter to track items, since the reading of FIFO function can tell you how many items is in the FIFO and also when it is empty.

  I recommend you the example of Communication of FIFO of RT which comes with LabVIEW to get an idea of how to use these functions.

• Huge memory leak - Simple to reproduce

  I have an application that updates the display from time to time using a timer, and I run the application it comsumes more in addition to memory. After some effort I reduced to a very simple scenario:

  The following code creates a matrix of 40 x 30 of objects that extend UIComponent (the same problem exists if I extend Sprite). A timer goes off every 3 seconds and repainted every object with a color at random on updateDisplayList(). This running (the Flex IDE or swf) produced an infinitely growing memory leak, even if no new memory must be allocated to each event of the timer. I see an increase of about .5MB to 1 MB to each call. The explicit gc() call (which I know I shouldn't) does not help. I'm using Flex Builder 3.

  What Miss me? Is this a known bug? Any comments would be greatly appreciated.

• Memory leak flow network with cluster of berries

  I use the network stream in sbRIO application, and I see a memory leak when endpoint RT is connected Windows endpoint. This happens with endpoints of chain and cluster tables parameters. I've attached an example that shows the behavior.

  I found this KB, which seems to explain the problem, but the solution it offers is just to spend on scalar types: http://digital.ni.com/public.nsf/allkb/784CB8093AE30551862579AB0050C429

  I can't do it in my application; I need scalar data with a block of channels multiple samples and send the package everything together (as seen in the typedef that I included with the attached example). How can I handle this without creating a memory leak which will eventually cripple my application?

  Never mind. Definition of the size of the buffer to a lower value, got flight' to stop. I had it so great that the buffer allocated is still all the time that I was monitoring the application. When I changed to 50 elements, he has only spent a few seconds allowance, then stopped the "leak".

• Windows 2008 R2 64 bit servers with UAG memory leak

  We organize two Windows 2008 R2 64 bit with UAG servers.  We note that, during 10-14 days memory begins to run upstairs and users no longer able to connect to OWA through UAG.  We found KB971265 which talks about the memory leak known issues and provides a fix for Vista.  However, we do not find a similar fix for Windows 2008 R2 64 bit.  Does anyone have a suggestion?

• [JS CS5] problem with memory leak possible with the dialog box in the event handler

  Hello

  I'm having a very difficult problem.

  I am attaching a script in a handler for a menu item, by using an installation script menu that I wrote based on one by Marc Autret. My version of the script menu installation attach a bunch of event handlers at the same time, to the actions of different menu.

  What is the event handler, with that I have a problem is to prompt the user for a URL and then applies the URL as a hyperlink to the text selection, with our house style for the way in which the URL should look like.

  The problem is the following:

  1. all other installed menu actions work very well, except for this one.

  2. the addition of URL script works fine, when you run it directly from the script menu.

  3. the combination of #1 and #2 (using the script to add URL by function as an event handler in the Edit menu) blocks to InDesign. But it is only after the addition of URL script has finished and done what it was supposed to do!

  4. when I comment on the section of the script URL adding user input, so that instead of saying

  userInput = myDisplayDialog();
  

  It is said

  userInput = "http://thisworks.com";   // userInput = myDisplayDialog();
  

  It works well as an event handler.

  So obviously a problem with the dialog box, but only when adding URL script is executed as an event handler. My first guess is that this is some kind of memory leak, but I think I am following the model of. destroy() the way I saw it elsewhere.

  Someone knows something like that before?

  I can provide all relevant if necessary scripts, but they are quite complicated. The most important of them is the input of the user function. Here it is:

  var myDisplayDialog = function( defaultText ) {
    
      var defaultText = defaultText || "";
      
      var myDialog = app.dialogs.add({
          name: "Type in a URL"
      });
      
      var myOuterColumns = [];
      var myInnerColumns = [];
      var myOuterRows = [];
      var myBorderPanels = [];
      var myTextEditboxes = [];
      var myInput;
      
      myOuterColumns[0] = myDialog.dialogColumns.add();
      myOuterRows[0] = myOuterColumns[0].dialogRows.add();
  
  
      myBorderPanels[0] = myOuterRows[0].borderPanels.add();
      myInnerColumns[0] = myBorderPanels[0].dialogColumns.add();
      myInnerColumns[0].staticTexts.add({
          staticLabel: "URL:"
      });
      
      myInnerColumns[1] = myBorderPanels[0].dialogColumns.add();
          
      myTextEditboxes[0] = myInnerColumns[1].textEditboxes.add({
           minWidth: 300,
           editContents: defaultText ? defaultText : "http://"
      });
      
      var myResult = myDialog.show();
      var myInput = myTextEditboxes[0].editContents;
      
      myDialog.destroy();
  
      if (myResult == false) {
            exit();
      }
      
      return myInput;
  
  }

• Windows Media Player ActiveX control causes memory leak

  I'm writing an application that will load and play *.avi files in an ActiveX control. The user must be able to load multiple files consecutively in the single player mode. However, it seems to be the memory leak every time that a file is loaded, even if it's the same file. For example, even when you load a small file in *.avi 81KO repeatedly, there is a memory leak ~ 6Mo coherent (as observed in the Manager of tasks). The leak memory is greater when I load larger files.

  I tried to deny it by adding using a Method Close by using the node invoke. It gets about 3 MB of RAM, but when I load the file again, it leaks ~ 9MB, leaving a net leak of ~ 6Mo once again.

  I also used reference close vi (s) to clear the memory ActiveX object, but that did not help either. In other versions of VI, I tried to eliminate the creation of a new IWMPlayer4 object using a shift register, but once again the leak memory persevered...

  It's a simple version of the VI, as well as the small video file attached. In my application, I want to be able to load large video files (~ 600 MB) several times without memory leaks. Thank you in advance for your help!

  Hi jareds.

  Thanks again for test it for me. I use Windows 7 and WMP version 12.

  As you requested, I tested it on a computer with Windows XP and WMP version 9 (and LabVIEW 8.2.1) and the problem of memory has disappeared. I then installed WMP version 11 on the same computer: still no memory problem.

  On the Windows 7 computer, I went back to version 11 using the instructions found on this link, and the problem of memory has disappeared. It seems that memory leak is due to a problem with WMP version 12 (although degraded version 11 on windows 7 has some bugs - and you can't go back to v12).

  Thanks again for the help!

• memory leak Winlogon.exe and high CPU usage

  I use Windows XP SP3. I'm leaking memory in winlogon.exe (about 5 M/hour). In addition, the CPU usage spikes to 50% of all 6 seconds. The file is properly signed so probably not a virus.

  This problem started after the application of last weeks patches.

  I seriously doubt that winlogon has a memory leak or people around the world would be screaming about it... and they are not.

  If this is what a thing look like, then you have another problem - probably a malware infection, or what you are currently using antivirus/antimalware protection is afflicted.

  Looking at previous answers, I would say that McAfee is afflicted, and it is already a well know that McAfee is a memory and CPU hog and you may want to consider replacing with something of less intrusive as Microsoft Security Essentials (do you use McAfee?).

  Since the Microsoft Answers forum does not have any kind of information system request when a new question is asked, we know absolutely nothing about your system.  Not knowing the basic information a problem prolongs the frustration and the agony of these issues.

  Thank you MS Answers, allowing the resolution of simple problems as frustrating and a lot of time as possible.

  Provide information on your system, the better you can:

  What is your system brand and model?

  What is your Version of XP and the Service Pack?

  What is your Internet browser and version?

  Describe your current antivirus and software anti malware situation: McAfee, Symantec, Norton, Spybot, AVG, Avira!, MSE, Panda, Trend Micro, CA, Defender, ZoneAlarm, PC Tools, Comodo, etc..

  What do you see (exactly) that you don't think you should see, and when you see it?

  If the system works, what do you think might have changed since the last time it did not work properly?

  No matter what you use for malware protection, follow these steps:

  Download, install, update and do a full scan with these free malware detection programs at:

  Malwarebytes (MMFA): http://malwarebytes.org/

  SUPERAntiSpyware: (SAS): http://www.superantispyware.com/

  They can be uninstalled later if you wish.

  The scans by operating clean, restart and fix any problems.

• On the user process start/exit Windows memory leak

  ECHO have first created a number of discussions and execution second order with them
  : output

  You start with 30 1000 arguments to have 30 parallel processors in batches, each compiles a 1000 times program and runs it. The problem is that the memory develops its use

  

  It's mine bug, you say? Where? In the end, I finished all batch processes. Memory consumption continued to increase. Yet, you see, he is not released. Is this ok? I noticed that my PC is starting to get excited. I can't even move a mouse after some 1000 CCG performs a loop with my simple program execution. PC becomes slow as hell and nothing helps to recover its restart performance but the machine. It seems that some memory leaks in Windows. It's not all recover when the process stops. Is this a known issue?

  It seems to be question of Windows Professional. I can't reproduce it in Windows 7 Enterprise, which also gets the requested CPU easily 100%.

• Massive memory leak to the Organizer 14 during the processing of faces

  Hello

  I have observed the Organizer 14 huge memory leaks during the processing of faces. My scripts:

  1. the Organizer 13 database with 35 k photos and faces named ~ 45. After the upgrade to v14, organizer began treating faces anew (preservation face name assignments v13). Now, for each photo ~ 6-8 k he consumed ~ 6GB of memory which was not returned to the system, where message memory and OS closing the Organizer. I have confirmed, that it was process organizer who was consumed by memory. I just finished finally all batch processing, and leaks memory have been persistent between the the computer reboots/restarts and restarts organizer - always at the same pace.

  2. After finishing above, I'm done with 12 batteries face k (right - 12 thousand - I have many faces). I started treatment, deciding faces unconfirmed for named faces and piles of face. After an hour or two of work, I'm done with the memory low Message for the Organizer again. What happened only once so far, but I guess because it was my first batch of work after the re-scan.

  Have you noticed something like that? I have screenshots of the Task Manager for the first scenario, and I think that I can easily do some for the second.

  I would like to report somewhere as well?

• Smart memory leak of Plugin

  Hello

  I'm writing just my first plugin smart - so far, I just write regular plugins. My first test was pretty simple, he just had a single slider ranging from 0 to 1 and filled it all out with black, white or gray the appropriate hue.

  However after the cursor to scrub back and forth several times all locked up. Task Manager to open (which took some effort) has shown that AE had eaten all of my memory. Running in the debugger, I found thatcalling filling consumed approximately 8 MB of memory, and then between the return of my AE chip make event and the call to free my AE pre_render_data had consumed on an another 8 MB of memory. Each cursor movement resulted in an another 15 MB or more be consumed and with breakpoints deleted making slowly slide from one end to the other consumed a few hundred MB.

  Then, I changed my plugin so that it completely ignores both made smart and smart prerender events. He has literally done nothing but return PF_Err_NONE. Always AE accumulated memory use. I still get 10 or 15 MB of memory leaks for each render event.

  Have you ever seen this type of behavior before? Is there something I need to make a smart plugin that I did not need to do before that could cause this problem? If necessary, I can post my sample code. I use Visual Studio on Windows 8.1 with AE CC 2012.

  It turns out that this is correct behavior. There is no bug. It's just the AE cached results.

  I downloaded the SDK of 2014 AE CC and built the plugin Smarty Pants here. I still see the same behavior. AE eats memory that I move the cursor backwards and forwards. However if I go to Edition-> Purge-> memory usage then falls to about 200 MB. By increasing the allocation of memory for other applications under Edit-> preferences-> memory & multiprocessing, I can limit the memory usage to an amount that avoids crashing the debugger.

• String memory leak?

  I've been programming for a while in AS3 and found something really weird with ropes which, without apparent reason, cling on memory, the program below changes just the property label.text with a random string, it works fine but when I looked at the Flex Profiler, I noticed that the number of channels increases steadly, I tried to run the garbage collector , but did not help me.

  What is a memory leak? How can I solve it?

  As I know that this strings must be collected by the garbage collector, because there is no object referring to them, yet this is not the case for all channels.

  Here is the code and a screenshot of the Flex profiler indicating the number of instances of String.

  Theres no such leaks memory, not answered here

• There seems to be a MAJOR problem (blocking/memory leak) in "subject: House", also known as the Firefox Start Page, at 26.0 Firefox on Windows!

  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 64

  None 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 again

  Sounds 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 bar

  You 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:
