Memory Leaks in OSX?

I've just maxed out the memory on my PBG4 so I've been paying closer attention to memory usage to see how much benefit I get. What I'm noticing is that the longer a program runs, such as Firefox, the more memory they take. At one point Firefox, with just one open page, was using 140MB of memory. I restarted the app and the memory went down to 48MB. I've noticed that the program can be idle in the dock and the memory still rises. I've seen this with other apps as well but Firefox is a good example. Is this common in OSX? I'm used to Windows so I'm sorta out of my realm here.

Yes, this is normal. My Safari will use around 238M after it's open for awhile. OS X manages memory very well though. Read these articles for more info:

Osx Lion memory leak: my MacBook pro is usable only 10 minutes after boot

Hi all,
10 minutes after boot it works just fine, but then it slows down and take centuries to open any application. Checked with Activity monitor:
on a boot, no user applications running: Free memory: 2,35 Gb, Wired: 459,7 Mb, Active 3 Mb, Inactive: 1,18 Gb
In 10 minutes, idle: Free memory: 8,4 Mb, Wired: 468,1 Mb, Active 2,36 Gb, Inactive: 1,17 Gb
Somehow all the free memory leaks to the active one, without me doing anything. I tried launching several programs to see if the memory will get adjusted accordingly, but it does not. Time machine is stopped. Tried disk repair is CMD+R mode, fixed permissions, killed most of the user processes - no success.
I've installed Lion on top of Snow Leopard a month ago and didnt feel any problems so far... Now my MacBook pro 2,4 GHz is completely useless, finally, after 6 years of seamless work :( Thanks, Lion
Any ideas how to deal with it?
Thanks,

I do not see anything like this on my system which would lead me to believe you may have a defective installation. So, my suggestion:
Install or Reinstall Lion from Scratch
If possible backup your files to an external drive or second internal drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Erase button and wait until the process has completed.
Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Install button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

I am getting a memory leak that sometimes leads to an unresponsive Firefox, but does not crash per se.

Hello, For the last couple of months, I am having issues with one of my tabs or the program itself causing a memory leak. I was hoping that subsequent releases would fix the problem, but when I downloaded V.11 it did not help.
I use tab mix plus and at any time, usually have about 25 tabs open. Everything functioned okay for 8 or so months up until recently.
I am wondering if there is a way to try to track down what is causing the leak. If it is one of my open pages, i will get rid of it. I tried opening one page at a time from scratch, but could not find the issue. .
I always have flash block enabled to cut down on the website junk.
using OSX firefox v11.

Now, I'm not going to say it's an Add-On problem because from the research I've been doing on this problem for the last half hour shows that everyone has DIFFERENT add-ons, but everyone's having the SAME problem....
So I went through my add-ons and disabled them one by one, and the single add-on that has been giving me grief is the latest WOT add-on. So, I have Firefox 11 (so does my wife) and we both have the WOT add-on. But that's where the similarity ends... I have Windows 7 x64, she has Windows XP x86.... but she doesn't have the memory leak problem.
What I see is a sawtooth pattern over time. Memory goes up a little over 30+ seconds, then drops down. But over half an hour, the peaks of the sawtooth are larger, and it doesn't drop back down to the same level again - always a little more than before. And before you know it, FF is peaking at 1.5+GB, dropping down to 1.2GB... and FF is running very, very slowly.... excessive disk accesses (paging probably, though I apparently I still have 1.5 to 2.0 GB of free RAM). Killing FF frees it all up, and if I open FF again, it's back to using 250MB of RAM.
So, it's not the add-ons per se, but how they're interacting with FF (or the other way round).... most likely, it's this plug-in container they created to stop add-ons from taking FF with them when they crashed. Seems to have created more problems than it has solved..... would be great if you could choose not to use it....

Performance and Memory Problems on OSX

Firefox seems to have some sort of memory leak. Even once I remove all the add-ons, and no matter which web pages, after about a day, Firefox is slow and I have to restart the browser. When using the diagnostics within Mac OSX, Firefox is consuming twice as much memory as Safari and is consistently the biggest CPU consumer. It would be nice if someone profiled the code and actually made sure it was optimized.

We are with the same problem. We read a lot about the vm in the RHAS 3.0. The vm was improved but, with bugs. We found a lot of inactive pages that, after the clean state, does'nt deallocate properly. This makes the thread kernel "kswapd" works a lot, taking all the cpu in the io process.
There is a known bug related to "kswapd" thread in the RHAS 3.0 kernel. The RedHat promess to solve the problem in the nexts releases (I really doubt it, because there was already 3 releases after its announces).
We have checked some strange behaviors too... The machines with Linux RH AS 3.0 + Oracle products (OracleDB and OracleIAS) are freezing randomically. We think that the shared memory are allocating kernel space pages, but we didn't found any evidences yet.
The workarounds (not tested yet):
- Upgrade to the latest kernel.
or
- Use the hugemem kernel (even when using less than 16GB of RAM, some guys reported that this solve the problem)
or
- Compiling a clean kernel directly from kernel.org. In this case, we don't have support from Oracle, but maybe the problem could be resolved until RH publish some bugless vm code with your kernel.

ITunes 6.0.4(3) memory leak

I know this topic has popped up on the Windows forum, but I'd like to officially document the same problem in iTunes for OSX.
Using the iStat Nano widget, I've been monitoring my memory usage when running iTunes. When I first start the program, memory usage jumps to 600 MB. The longer iTunes is open, the more and more memory disappears, whether I'm actively using the program or not (i.e. listening to music). Eventually, this causes a hard crash. By hard crash I mean that I must use the on/off button to reboot the machine. I have had this problem since getting my computer (in mid-March), so there has been at least one iTunes update since then that has not fixed this issue. (I have a previous post on this topic called "iTunes freezing" that was made before I realized that it was caused by a memory leak.)
I am very, very pleased with my MacBook Pro and I realize that this is not a hardware issue. Has anyone else encountered this problem? Are there any plans to fix it in a future update?
Thanks in advance for any comments, suggestions, or solutions!
2.16GHz 15.4" MacBook Pro, 2GB RAM Mac OS X (10.4.6) 4G 40GB Photo iPod, 5G 2GB nano

I posted a question this evening on what sounds like the same issue: the link is here:
http://discussions.apple.com/thread.jspa?threadID=548752
I think your original post makes clear that this issue is about iTunes itself, it's not about any devices or iPods, not is it to do with the Intel or non-Intel processors... I will try looking at the Memory stats too.
What baffles me is that I had been using iTunes 6 for quite a long time (and only updating it manually, not automatically) before I ever experienced this.
My hunch (but what do I know?) is that my initial freeze might have happened for some other reason (too many applications working hard at once, as sometimes happens -- though I have had this happen reasonably often on the PowerBook it is extremely rare on the G5) -- and then in the course of that freeze / crash something in iTunes got corrupted (perhaps the database file that allows iTunes to navigate the iTunes library?)
By the way, what is the technical name for the total freeze thing (i.e. no beachballs, just complete loss of the mouse and keyboard response, clock stops, no shortcuts working, only PowerButton allows you to shut down).
Has anyone with this issue tried uninstalling iTunes (by Trashing the App) and reinstalling from a newly-downloaded copy? (I might try that ...)

Still memory leaks with 10.8.4

I hoped 10.8.4 could solve the issue..
Unfortunately I still have memory leaks, pages out and inactive memory full for a lot of programs running. First of all FCX importing and transcoding full the inactive memory, and OSX slows down, swapping to the SSD. The same problem with all (4 in total) macs mounting ML.
Has anyone solved the problem please?
Thanks in advance.
Attilio

Attilio, although I'm not a Final Cut user, I suspect that your problem is, as Kappy first said - insufficient RAM.
See: http://forums.macrumors.com/showthread.php?t=1332888 for instance.
It's a RAM hog. With the Retina, you're stuck with the RAM you've got now, unfortunately. With any other hardware, I'd consider boosting the RAM as much as you can. I don't run FCX or any video editing software (I build web sites - so I use Dreamweaver, Photoshop, Lightroom etc.) and I boosted the RAM in my Mac Pro to 18GB quite a while ago because I was seeing a lot of pageouts and slowdowns with 10GB. I do tend to have a ton of windows and apps open at once.
See also: https://discussions.apple.com/thread/4759586?start=0&tstart=0 - Kappy's very good explanation of memory usage and various links to check.
Whether it appeared to run better in SL or not, I can't really say - unless you ran two identical Macs, side by side doing exactly the same things in FCX with the two operating systems installed, I don't know how one could accurately assess that.

Yosemite and Mail massive memory leak and excessive CPU usage

I've just installed Yosemite and upgraded to 10.10.2 via the AppStore. Now I have a problem with Mail sucking up all the CPU (>106% !) and memory (>8Gb and rising while doing nothing). Everything runs fine when I quit Mail. Very disturbing behaviour!
I've tried several suggestions found elsewhere on the board here, such as turning off and even removing all Mail plug-ins including SpamSieve, but without positive results. I've tried un-selecting 'Store draft msgs on server', as well as the option for junk and sent msgs. but again without any difference. Going Offline within Mail also makes no difference to its memory hogging or CPU usage.
I notice this is an issue that's been around since last year (wish I'd known that before upgrading to Yosemite today) and I am just completely flabbergasted that it still exists. Would've thought Apple'd have fixed it in the first but certainly in the second incremental OSX Yosemite release.
Is there anything else I could try that's proven to be effective in stopping Mail's massive memory leak?

Okay, I've run Disk Util and restarted. Seems to have made a little bit of a difference to the RAM gobbling in that it appears to be going at a slower rate, but it's still up at around the 45Gb after an hour. Here's the EtreCheck report in the hope that it helps.

FCE "out of memory" - QT7 memory leak ?

when I try to render a large number of audio clips in FCE, after rendering about 15 mins of clips, it stops with "out of memory" error.
when I look at Activity Monitor while this is happening, I see the VM figure for the FCE process grow and grow until it hits 3.50GB then the error is thrown.
It looks like a memory leak ... with each clip some VM is allocated but not released and eventually the allocation hits an OSX/hardware limit.
the behaviour seems to have started since upgrading from QT6 to QT7.
have others observed this ?
my current workaround is to select 12mins of audio, render the selection, exit FCE to release the VM, open the project again and repeat. very time consuming.

I also have this problem, and stumbled onto the same workaround as others: render ~15 minutes of audio, quit, restart. A real nuisance!
I also have seen the rendering of audio "complete", but in fact the audio disappears after some point in the (long) clip. I haven't found any way to re-render it, so I've been forced to reimport the whole clip and start over. Arrrgh! Any of you seen this problem?
From the symptoms, the root cause does seem to be a memory leak in the audio code (QT?) There's a QT forum posting that seems to indicate the same.
Any comments/prognosis from anyone at Apple?

How to determine memory leaks?

I tried in XCODE, the RUN/ Start with Performance TOol / and tried out the various options. I was running my app and looking to see if it would report increasing memory use but it seemed to be looking at my total system (i was running under the simulator). In general what is the recommended procedure for determining memory leaks, which tool to use, and what tracing can i use?
How does one look at the retain count of an object? are there system routines that have knonw leaks?

You took the right path. Once instruments comes up select the Leaks tool. Turn off automatic leak detection. In your app, start off at some known state, do something, and come back to the known state and check for leaks. For instance start off in a view, do something that brings up another view then come back to the original view and check for leaks. Leaks will show you if you leaked. Since you took a very deterministic path then checked it should be straight forward to go to the code and find / fix the leaks. Leaks shows you where the code where the leak was generated.

Memory leak in JSpinner implementation (maybe others?)

Hi,
I am developing an application using Java and Swing, and have run into some problems with memory leaks. After examining the source code and making an example program (provided below), I can only come to the conclusion that there is a bug in the implementation of JSpinner in Sun Java 1.6.0_03.
If one uses a custom model with the JSpinner, it attaches itself as a listener to the model. However, it never removes the listening connection, even if the model is changed. This causes the JSpinner to be kept in memory as long as the model exists, even if all other references to the component have been removed.
An example program is available at http://eddie.dy.fi/~sampo/ModelTest.java . It is a simple swing program that has the JSpinner and two buttons, the first of which writes to stdout the listeners of the original model and the second changes the spinner model to a newly-created model. A sample output is below:
Running on 1.6.0_03 from Sun Microsystems Inc.
Listeners before connecting to JSpinner:
Model value is 0, 0 listeners connected:
Listeners after connecting to JSpinner:
Model value is 0, 2 listeners connected:
1: interface javax.swing.event.ChangeListener
2: javax.swing.JSpinner$ModelListener@9971ad
Listeners now:
Model value is 8, 2 listeners connected:
1: interface javax.swing.event.ChangeListener
2: javax.swing.JSpinner$ModelListener@9971ad
Changing spinner model.
Listeners now:
Model value is 8, 2 listeners connected:
1: interface javax.swing.event.ChangeListener
2: javax.swing.JSpinner$ModelListener@9971adThis shows that even though the model of the JSpinner has been changed, it still listens to the original model. I haven't looked at other components whether they retain connections to the old models as well.
In my case, I have an adaptor-model which provides a SpinnerModel interface to the actual data. The adaptor is implemented so that it listens to the underlying model only when it itself is being listened to. If the JComponents using the model were to remove the listening connections, it, too, would be automatically garbage-collected. However, since JSpinner does not remove the connections, the adaptor also continues to listen to the underlying model, and neither can be garbage-collected.
All in all, the listener-connections seem to be a very easy place to make memory leaks in Java and especially in Swing. However, as I see it, it would be a simple matter to make everything work automatically with one simple rule: Listen to the models only when necessary.
If a component is hidden (or alternatively has no contact to a parent JFrame or equivalent), it does not need to listen to the model and should remove the connections. When the component is again set visible (or connected to a frame) it can re-add the connections and re-read the current model values just as it does when initializing the component. Similarly, any adaptor-models should listen to the underlying model only when it itself is being listened to.
If the components were implemented in this way, one could simply remove a component from the frame and throw it away, and automatically any listener-connections will be removed and it can be garbage-collected. Similarly any adaptor-models are collected when they are no longer in use.
Changing the API implementation in this way would not require any changes to applications, as the only thing that changes are the listener-connections. Currently used separate connection-removing methods should still work, though they would be unnecessary any more. The API would look exactly the same from the view of an application programmer, only that she would not need to care about remnant listening connections. (As far as I can tell, the current API specification would allow the API to be implemented as described above, but it should of course require it to be implemented in such a way.)
Am I missing something, or is there some valid reason why the API is not implemented like this?
PS. I'm new to these forums, so if there is a better place to post these reports, please tell me. Thanks.

Another cognition: It's the following code, that causes the memory to be accumulated:
obj = m_orb.resolve_initial_references("NameService");
ctx = NamingContextExtHelper.narrow(obj);For the first 4 calls to this code the memory usage of the nameservice is unchanged. From the 5th to the 8th call, it's increased by approx. 10KB per call. And thenceforward (beginning with the 9th call) it's increasing by approx. 10MB.
What's going wrong here?

Memory Leaks   Unresponsive Mouse

2009 8 core Mac Pro w/ 24 GB of RAM, ATI Radeon 4870, and a SeriTek PCIe eSATA card (card only has drives connected when running a manual drive clone). When running Toast 10 or Parallels 9, my RAM will fill up (I use a program called Menu Meters to monitor stuff). This machine worked just fine under OS 10.9 and earlier - no issues like this at all. ClamXAV will also completely fill the RAM up (the meter will be full green, instead of part green, then mostly grey when Toast or Parallels fills it up). I have to use Terminal to purge it so that the machine is usable.
The other thing that happens is that sometimes when the computer wakes up or I am in the middle of doing something, the mouse will still move, but the dock will not pop open and the left button the mouse doesn't respond. The right button will open the right click menu, but will not respond normally at all. I have tried a different Magic Mouse, but the problem is the same.
I thought that it may be a problem with the factory RAM and the Kingston RAM not playing nicely together. So I ran it with just the factory 8 GB and then ran it with the Kingston 16 GB - the problem persists no matter which RAM is installed. All of the RAM also passes the memory tests in Rember and TechTool.
So, I need to find out if someone thinks that maybe the bluetooth module may be going bad causing the mouse issues. I also need to find out what is causing the memory leaks. I followed the steps that someone gave on this site to boot into safe mode, repair permissions, reset PRAM, then reset SMC (or the other way around - I did it like they said to). It did nothing to fix the problem.
I need some guidance here. As I stated early on, the machine worked perfectly with OS 10.9. I have WAY too much software that I use, so doing a completely fresh install is out of the question - I don't have time to reload everything. This problem is annoying and I know that I am not the only one having these issues. Any input will be greatly appreciated. Thanks in advance.

Here is the EtreCheck report:
Problem description:
Memory leaks when using Toast 10 or Parallels 9. Mouse also become unresponsive (it will move, but left button does not work and dock will not pop open - mouse problem happens independent of the RAM being filled up - different mouse was tried with same result).

T61 with memory leak on XP for driver battc.sys

Hi
I have an issue with XP where the battc.sys module that is part of Windows XP and responsible for the kernel side of monitoring the battery status. This module continually leaks memory until I have no more kernel paged resources left and programs start to fail on my laptop.
I raised a support case for this with Microsoft and after some investigation and upgrading to the latest T61 power drivers that were released a few days ago on the Lenovo site, MS support told me it is a fault of the T61 and that I would need to disable Microsoft APCI support to stop this memory leak from occuring and to take the issue up with Lenovo.
I have used the verifier tool to confirm that it is the Windows XP SP3 battc.sys memory module leaking.
I am running the latest T61 drivers and fully patch with MS drivers on SP3.
As MS have told me it is the fault of the T61 I am posting this issue here.
Thanks
Stephen

It is memory available to the kernelwhich itself does not show under a process in task manager as far as I am aware (unles it is taken account as part of the system process).
The best way to measure the available kernel memory space available is by using sysinternals procexp.
You need to download procexp and also install the windows debugging tools from Microsoft. Then in procexp set the "Options > Configure Symbols : Debughlp.dll path" to the new debughlp.dll installed with your debu tools and set the symbols path to srv*c:\Symbols*http://msdl.microsoft.com/download/symbols
Then you can choose in procexp "View > System Information" and see the used and total paged and non-paged kernel memory space.
poolmon helps monitor all the symbols that are taking up this memory and verifier lets you drill down to the exact module and the changes in memory for a module that is occuring.
Here are two really good links on it
http://blogs.msdn.com/ntdebugging/archive/2006/12/18/Understanding-Pool-Consumption-and-Event-ID_3A0...
http://blogs.msdn.com/ntdebugging/archive/2008/05/08/tracking-down-mmst-paged-pool-usage.aspx
In my poolmon i notice that Mmst and battc are taking alot of memory after my computer has been running for some time. Mmst being high is normal but battc should not continually be growing as it is which is why I raised the case to MS but they want verification it is not a Lenovo issue.

How do I report a major memory leak problem with Firefox 3.6.10 in WinXP?

After I installed Firefox 3.6.9 on a WinXP desktop, I occasionally had minor memory leak problems, reflected by getting "out of virtual memory" messages. I upgraded to 3.6.10 when notified that it was available and that it supposedly fixed stability problems. Ever since then, whenever I use Firefox, it starts out quick as a flash, but very rapidly slows down to a crawl, and has twice brought my system to a halt. IE does not cause this, nor any other program I use, but the execution speed of all programs slows as badly as Firefox. If I knew where to get older versions, I would back up to 3.6.9 or earlier. The situation now prevents me from using Firefox much at all.

Im running windows 7, Firefox 3.6.10 and before i updated to 3.6.10 my CPU never went above 10% with Firefox open. Now it can spike well above 50% and i have nothing different from when i had 3.6.9 to now when i have 3.6.10.
There is no evidence for me to suggest one of the additions i have is causing it, its all pointing to Firefox itself and the last update.

How can I address a memory leak problem with Firefox?

I have happily used Firefox for the past 7 years, and have rarely had difficulties. However, I am having some trouble now; Firefox (running 3.6.6) seems to have a memory leak on my machine. It's slower than what was discussed in other forum posts, but it still scales up slowly to multiple hundred MBs of Memory with very little CPU usage.
I have tried disabling add-ons and extensions, but this does not stop the problem. I have cleared my cache and other stored data, but that also does not help. Has anyone experienced a similar problem that might be able to help?
== This happened ==
Every time Firefox opened
== within last two weeks

Hi reble0708,
I have Java console disabled on my Firefox browser.Everything is working fine for me. There maybe other problem on your browser which is making PDF document faded and blurry. Can you post the link where you found the problem viewing the PDF document?
Btw, you can go to ftp://ftp.mozilla.org/pub/firefox/releases/ and select the previous version of Firefox from the given options. There's no need to uninstall Firefox before you downgrade to the previous version of it.But before new installation, backup your Firefox profile folder.
edit: replaced random unofficial download site link.

Allocated memory pool was not deleted! 1 GB memory leak is too much for me!

Dear Sirs. I found that DB environment, that was configured to use 1 GB cache size, won't free it when closed! Why? First I tried to open and close environment and got the following:
Detected memory leaks!
Dumping objects ->
{596} normal block at 0x01970040, 1048596 bytes long.
Data: < > 14 00 10 00 DB DB DB DB 0B 00 10 00 01 00 00 00
{578} normal block at 0x00397978, 464 bytes long.
Data: < > D0 01 00 00 DB DB DB DB C7 01 00 00 01 00 00 00
Object dump complete.
I have and idea that BDB will reuse the memory, rite? OK, let's try to create the same environment and open it. After environment was opened, closed, opened again and again closed, I got the following:
Detected memory leaks!
Dumping objects ->
{3663} normal block at 0x01B80040, 1048596 bytes long.
Data: < > 14 00 10 00 DB DB DB DB 0B 00 10 00 01 00 00 00

Data: < > D0 01 00 00 DB DB DB DB C7 01 00 00 01 00 00 00
Object dump complete.
So memory was not reused, nor deallocated.
By the way, you may be interested in other leak I found, but fixed, see
Replication manager memory leak when setting local site information.
This leak is more serious, I am not sure I will fix it quickly. Maybe I'm doing something wrong? Could you please suggest something?
Thanks in advance!
With regards,
Vladislav.

OK, the problem solved by fixing code in file 'log.c', method '__log_dbenv_refresh'.
Just added the code that deallocates memory of bulk buffer.
if (IS_ENV_REPLICATED(dbenv))
if (lp->bulk_buf != INVALID_ROFF)
__db_shalloc_free(&dblp->reginfo, lp->bulk_buf);
lp->bulk_buf = INVALID_ROFF;
lp->bulk_len = 0;
lp->bulk_off = 0;
It was allocated in the '__log_open' function, by the following code:
          lp->ready_lsn = lp->lsn;
          if (IS_ENV_REPLICATED(dbenv)) {
               if ((ret = __db_shalloc(&dblp->reginfo, MEGABYTE, 0,
               &bulk)) != 0)
                    goto err;
               lp->bulk_buf = R_OFFSET(&dblp->reginfo, bulk);
               lp->bulk_len = MEGABYTE;
               lp->bulk_off = 0;
          } else {
               lp->bulk_buf = INVALID_ROFF;
               lp->bulk_len = 0;
               lp->bulk_off = 0;
Sorry for time taken to read my posts, I was really needy in quick help, but solved problems myself.
