Firefox memory leak <;! DIFFICULTY! >;
Hello fellow Firefox users!
For most of us, Firefox suffers from a memory leak crazy, this can cause slowdown and perhaps even crashes. This happens mainly because when you close the tabs, the RAM, they took is always taxing your computer. Among other things cause this annoying leakage.
Recently, I switched to Firefox and has this leak. I would not put upward with him, so I put solutions. Here's what I came with.
Some addons I've handpicked, which when combined, are extremely effective.
Firefox slow acting? Try these great modules!
Get all these together and make a leak free and faster Firefox!

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).
There seems to be a MAJOR problem (blocking/memory leak) in "subject: House", also known as start up Firefox, 26.0 Firefox Page, Windows!
-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.
-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:

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.
I have PSU8CE 18 p Satellite U500 with preinstalled Windows7 Home Premium x 64 with 4 GB RAM. When I start mode safe then memory not sunk. When I start it in Normal mode then nonpaged kernel memory develops up to 3011 MB (~ 4 days running).
I downloaded poolmon.exe and Crescent pool tag found: "AmlH" (ACPI AMLI Pooltags). In safe mode, this pool has 1 single allocation unit. In Normal Mode ~ every 73 seconds he returned new unit. Size of each unit is 524288 bytes.
Then I downloaded and installed "Windows Performance Toolkit" and run xperf.exe and xperfview.exe according to

I restored windows to State factory but still present memory leak.
Memory leaks are a common error in programming.
leak memory occurs when a computer program consumes memory, but is unable to release it in the operating system.
In your case, it would be necessary to know what application or process that runs in the background do
This can be very long process you would need to install a system of fees will need to check the memory leak after each installation of driver or another application
Hey everybody. I'm having a problem with my MacBook Pro (retina, mid-2012), where he is recovering in market (usually after gel). In this case only (so far) while using Adobe Illustrator CC 2015 (to date). I also use a Wacom tablet (intuos 4, with latest drivers), drawing, which can also be the culprit.
This happened with Yosemite, so I had upgraded to El Capitan - that does not solve the problem.
I apologize if the problem is with myself! I get that this problem is probably the fault of Wacom, Adobe or myself - I just want to see what you think Mac-heads.
Thanks a lot, a lot in advance for any advice - I appreciate any help I can get.
The report I get, when restarting is as follows:

Two problems have been caused with my HP Split 2 x since I bought it 2 months ago:
(1) the touchpad works sometimes for a few seconds, while the touchscreen still work OK.
(2) the computer becomes slow after a while of use (which varies from a few minutes to a few hours usually). The Task Manager shows 98%-99% of memory, most of which use (3.6 GB / 4 GB) are not paged memory.
I suspect the two issues are related to a faulty Synaptics driver, according to:
I did the same test as the second link with the same result: Open "Task Manager" (Ctrl-Shift-Esc), on the 'Performance' tab, select 'memory '. Note the value for "Non paged memory. If I move the touchpad, it increases to about 1 MB every 5 seconds. If I stop moving, the value remains constant.
I use the preinstalled Synaptics driver, version 126.96.36.199 (Sep 06, 2013) for 64-bit 8.1 window.
Everyone has the same problem, or use it without these issues?
I would like to know if a restoration system or factory reset may fix.
Microsoft has just released an update for Synaptics Driver, not thanks to HP which has not found a way to provide the possible Synaptics driver as an OEM update.
Update Windows Update to Sypatics HD TouchPad two days ago, but I would not be allowed to install as it kept then mainly in giving the 800F0100 error Code. After some research on the Internet I could find that an installation manual after the WU has downloaded the driver would be possible.
So I went to the Device Manager > mice and other pointing devices > TouchPad Synaptics HID > properties > driver > Update Driver > Browse my computer for driver software and shown the finger/windows/C:\Windows\SoftwareDistribution/Download and everything worked like a charm = D
I have no more memory leak and now after SEVEN MONTHS I finally can use gestures that it was supposed to.
But I still annoyed gel problems which in my case is a dysfunction between the screen and the dock.
Just that you wanted the guys at Microsoft to know is the solution, not the HP that would have had if they have signed and put the driver since November last at our disposal. Blame it on you, HP.
I wonder if anyone has had problems with memory leaks/Lakes when you use UDP and data queues?
The program has a section of code where the queues are loaded with the data read from different UDP ports. The queues are then read by a loop (which is triggered by a source of synchronization of 1 kHz) and some of the data is displayed on the Panel before the main VI. When the program runs it loses memory about 100 Kbps leading to a failure in about 4-5 hours, when the physical RAM is at its maximum.
I think that I traced the question (using the DETT it shows several memory allocation operations) to the Subvi I join which fills the queues. Can anyone help to emphasize something that could lead to leaks of memory/Lakes?
I suspect that the problem is that you are not emptying queues quickly enough. And is not in the code you have posted. There's also a few subVIs, classes, and controls.
Usually call loops should only be used on real-time operating systems. They offer no advantage over the standard while loop and have an additional charge when using a desktop OS. Also placing indicators within the quick loops can create problems. The operating system does not update the screen dozens of times per second, so wrote indicators 1000 times per second LV forces or the operating system, or both to manipulate data.
Having multiple synchronization methods in a loop can lead to problems. UDP timeout is probably based on the clock count of ticks. If you have the timeout of read of the UPD defined with a value greater than zero, the UDP bed may take longer than the timed loop interval. The timeout of read UDP allows a wait in a standard while loop.
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.
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?
Seems to be leaking memory associated with ToolTips. Every time I put your mouse on a panel using tool tips I see case the dynamic memory usage constantly increases. If I comment out the call to the functions of the tool tip (i.e. SetCtrlToolTipAttribute), memory leak disappears.
There is no patch for 8.0.0, if it is tell you.
But from the Toolbox of the programming interface is open-source, you can easily fix it yourself:
The 8.0.0 3365 online version of C:\Program NIUninstaller Instruments\CVI80\toolslib\toolbox\toolbox.c, you need to add the function call following ListDispose:
If (RectContainsPoint (bounds, point))
PointConvertCoordinates (Panel, child, & point, FALSE);
Return PointToPanel (child, point);
After you make the change, you will have to recompile the file (Options > create a file object) to regenerate the object file and restart CVI.
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?
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.
I use TDMS to store test data that seems to be causing a memory leak in my (very convincingly) program. Below is a graph of the three versions of my program. Series 1 uses storing data open PDM, the data file added and closed every 5 seconds. Series 2 uses storing data PDM with a referense remaining open during operation and closed at the end 3 series written data in a CSV file. The charts show the use of LabVIEW memory each seconde.5 ~ 4 hours of a 10 hour test.
Windows XP SP3
Further explanations... when a TDMS file is opened, LabVIEW will create an index in memory structure that is used for random access to the file. The Streaming API integrated LabVIEW TDM will always create the index, even if you just write. The size of the index is not dependent on the size of the file, but on how fragmented file is. If you store a relatively small number of large blocks of data, the index will be very low. If you keep adding small amounts of data on your record, it could make big enough. A cure for this is the property of NI_MinimumBufferSize. You can set this property on a channel to the LabVIEW to a number of values of the buffer before storing. In this way, data from multiple calls to 'Write TDMS' counts as a data segment in the file. Typical values for this are 1000 or 10000. Fragmentation of files and memory footprint are reduced accordingly, but LabVIEW uses little memory for buffers.
If all else fails and you do not have access to the file of reading while you write, you can also use the VI-based TDMS API. This will not build the structure of the index that I mentioned above, so there should be no increase in memory at all. In this case, I recommend to defragment files front of post-processing.
Hope that helps,
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".
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!
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!
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?
