The faster the loop speed and the network connection, the faster mozilla will consume memory. Reproducible: Always Steps to Reproduce: 1.Browse to URL (example) http://mirror.bom.gov.au/products/IDR022.loop.shtml 2.Leave it on the site 3.Increase the loop speed to reproduce it faster (not necessary but makes reproduction easier) 4.Wait and watch memory usage Actual Results: Memory usage increases with time. It seems to cache every next image. Expected Results: Should only cache the last four images and not use up any more memory.

WFM 2001111303 on Win2k; Mozilla's memory usage stays at a steady 143 MB. -> ImageLib, but punt as needed

I see it in 2001110908 too (MacOS 9.2.1). Memory usage quickly jumped from 35MB to 73MB. When I forced a GC by opening a new window and closing it again (while the loop was still running), the memory dropped back, but started to climb again. When I closed the window (killing the loop), and forced another GC, the memory was back to 37MB.

Confirming on yesterdays CVS build under Linux.

WFM, my memory usage stays normal with 0.9.6.

Definitely still occurs in 0.9.6 with my linux build.

Con, did you try a fresh profile?

Yes, I just tried it now and it still occurs. It is more pronounced on the 256km loop than the 128km loop, but definitely keeps soaking up memory with a completely fresh profile.

Just checked back and I also leak memory. Don't know why I did not notice earlier today...

*** Bug 115474 has been marked as a duplicate of this bug. ***

Confirmed as also occuring on mozilla 0.9.8 on Windows NT4

Please retest this with a nightly, I do not see the leak anymore with my fresh CVS build.

Hmm, still there with Linux 2002020821, though not as pronounced as it used to be.

Tested on WindowsNT and Linux with the tip of cvs dated 19th feb'02. I am unable to reproduce the bug.

Tested on WindowsNT and Linux with the tip of cvs dated 19th feb'02. I am unable to reproduce the bug.

Just compiled from fresh CVS. Be patient, memory usage _will_ increase. This has been slowed, but it is not gone. REOPENING.

I was seeing something leak, however, I don't believe it was images. I will try and run this through purify.

I have tried the following but could not reproduce the bug. a) ran it on Linux overnight top for the bug#110048 on Linux at 9:40 pm on 26 th feb'02 16969 nivedita 9 0 35424 34M 25032 S 5.8 13.9 0:27 mozilla-bin top for linux at 9:00 AM on 27 th feb'02 16969 nivedita 9 0 36164 35M 25040 S 5.7 14.2 39:17 mozilla-bin b) ran it on WINNT as well and did not see any significant change in memory. c) ran it through purify but could not see any potential leaks in the image lib. pavlov, Did you have a chance to run purify other this url?

Nivedita asked me to verify this again, so I downloaded Linux 2002022821 and tried again. I untarred it and ran it vanilla without any plugins. Steps to reproduce: 1. Open URL. 2. Use the ">" control to the right of the map for making the animation quicker and make it absurdely fast. All seems fine. 3. Now slow down the animation via the "<" button. 4. Mozilla starts leaking big time. I ran top in the background to measure memory consumption. The memory lead seems almost gone with the fast animation, I could barely reproduce it. With the slowdown it does get very visible, though. I run an up to date Debian testing system with XFree 4.1.0 and glibc 2.2.4. If you need further details or assistance, contact me, I will gladly run any tests you might need. I suspect that purify is a commercial product, otherwise I might try to run it myself. Con, Johan, the others on the CC list, please try to verify this and provide some steps to reproduce or tell us if you do not see the problem.

I use the adzapper filtering proxy. It does somehow exacerbate the problem. Just tried again with Mozilla and a terminal running top as the only processes in my GNOME environment and without adzapper. The Leak still occurs, albeit less pronounced. Just play around a bit with the speed controls and memory usage will go up. Nivedita, maybe installing adzapper (it's free software) will help you see the problem, but it does occur without it. http://www.zipcon.net/~adamf/adzapper/

I am no longer seeing the problem (linux latest 0.9.9 build 2002030414)

Yes, I just tried to reproduce this with my current CVS build, no memory leak anymore. Hooray! Marking WORKSFORME. Con, if you still cannot reproduce this following my instructions, please mark this VERIFIED. Thanks.

Woohoo it's gone. I am unable to reproduce this bug any more :-)

Oh dear. This has come back with a vengeance in 1.0rc2 on linux. I haven't tested it on any other platform but it's seriously sucking memory again (build 2002051009)

Yes, this leaks with 1.0RC2 under Linux. I also tried 2002051809 from the 1.0 branch and I get increased memory usage after twiddling with the speed settings a little bit. It does not appear to grow completely out of bounds, however.

wfm win2k sp2, mozilla 1.1a 2002061104

WFM with trunk 2002062304 on WinME.

Ok, it does keep downloading the images from the server and allocating memory for them. In 10 minutes, allocated data rose from 64MB to 111MB, in memory data from 54MB to 88MB, and in use data dropped from about 32MB to 24MB. After about 10 minutes, mem usage dropped back to 66MB, 53MB, and 24MB. After 20 minutes: 67, 54, and 25MB, respectively. I increased, stopped, then decreased the loop speed (set to bounce), checking memory usage with WinTop. i'm using a PIII900, with 256MB RAM, cable connection, Mozilla memory cache at 4096KB, and disk cache at 12000KB.

This does indeed seem to get exacerbated by using a proxy. I tried again with adzapper and it leaks. It's not as fast as it used to, it may take some minutes before it gets noticeable.

I am seeing this problem on Linux with Mozilla 1.1a (Build 2002061108) The interesting thing is that it is not the mozilla process which is chewing up the memory; it is the X server. This suggests that the problem may be in the allocation of X server-side resources such as pixmaps. Below are before and after output from top (sorted by memory use). --------------------------------------------------------------------------- 11:03am up 23:52, 11 users, load average: 0.05, 0.03, 0.00 108 processes: 105 sleeping, 3 running, 0 zombie, 0 stopped CPU states: 2.9% user, 4.5% system, 0.0% nice, 92.4% idle Mem: 191088K av, 161800K used, 29288K free, 0K shrd, 3248K buff Swap: 297160K av, 54140K used, 243020K free 78568K cached PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME COMMAND 1088 root 12 0 59052 49M 7664 R 1.3 26.4 7:50 X 11373 john 9 0 35404 34M 14772 S 0.0 18.5 1:53 mozilla-bin 11375 john 9 0 35404 34M 14772 S 0.0 18.5 0:00 mozilla-bin 11376 john 9 0 35404 34M 14772 S 0.0 18.5 0:01 mozilla-bin 11377 john 9 0 35404 34M 14772 S 0.0 18.5 0:00 mozilla-bin 11379 john 9 0 35404 34M 14772 S 0.0 18.5 0:01 mozilla-bin 11443 john 9 0 35404 34M 14772 S 0.0 18.5 0:00 mozilla-bin --------------------------------------------------------------------------- 11:07am up 23:56, 11 users, load average: 1.05, 0.48, 0.18 109 processes: 108 sleeping, 1 running, 0 zombie, 0 stopped CPU states: 9.5% user, 12.9% system, 0.0% nice, 77.5% idle Mem: 191088K av, 188680K used, 2408K free, 0K shrd, 280K buff Swap: 297160K av, 170388K used, 126772K free 60636K cached PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME COMMAND 1088 root 15 0 219M 115M 3716 S 4.1 61.8 8:01 X 11373 john 18 0 28132 15M 8412 S 6.8 8.3 2:04 mozilla-bin 11375 john 9 0 28132 15M 8412 S 0.0 8.3 0:00 mozilla-bin 11376 john 9 0 28132 15M 8412 S 0.0 8.3 0:01 mozilla-bin 11377 john 9 0 28132 15M 8412 S 0.0 8.3 0:00 mozilla-bin 11379 john 9 0 28132 15M 8412 S 0.0 8.3 0:01 mozilla-bin 11443 john 9 0 28132 15M 8412 S 0.0 8.3 0:00 mozilla-bin

This bug can be reproduced at some U.S. .gov and .edu weather sites. See bug 127825, which appears to be a dupe of this bug. I also see the added behavior of the animation becoming populated with duplicate images...quite annoying. Also, we have ImageLib tracking bug 158715. Should this bug be added to that tracking bug's list?

*** Bug 127825 has been marked as a duplicate of this bug. ***

OK, some info from the dupe: Also happens on this URL and it also memleaks the X server. http://www.crh.noaa.gov/grr/forum/derecho_anim.html

I've had this for sometime too. For me, Mozilla forces a leak in the X server. It's not uncommon for the X server to be taking up over 300M of swap after a few hours of doing nothing but browsing. I suspect it's not releasing pixmaps, GC's, fonts, or something in the X server. I'm currently running 1.0 on Linux (RH7.2 & Suse 8.0 under KDE), but I'm about to upgrade to 1.1 in a few minutes. If that fixes it, I'll report back. BTW, a really inconvenient work-around is to boot your machine into run-level 3 (non-X), then when all of your swap and RAM are about to be used, exit your X session. That will release most of it. As root, turn off all swap, then turn swap back on; that will force the rest to be discarded. Now you can run startx again, being at less than 40M of memory total (like you were when you first booted).

This bug was reopened after TM was set. Resetting TM. From descriptions of the problem it doesn't sound very "Rapid" any more. If that's the case can someone correct the misleading summary. Thanks.

Sounds related to bug 81446.

Are You sure about the duplicate? In my case, it does not grow with time, it just grows while loading. Then it can loop forever without more growing. And if I close the site in any way, it shrinks to 25MB. And it is the mozilla-bin, not the X. It seems not like a memory hole, but just a simple implementation. The browser saves all decoded frames in memory, without any compression. I think GIF is anyway thwe wrong format for this animation. A vector format (Flash) would be much better. But users of other browsers report that they handle the giant GIF gracefully.

This bug also occurs on Win2K

The problem is still in the very last firefox release (but not in mozilla suite) try http://facs.scripps.edu/surf/images/euranim.gif

All of the test cases posted in this bug WFM with the current trunk. I see no change in memory usage once the image has fully loaded and is allowed to loop indefinitely. Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a2pre) Gecko/20061220 Firefox/3.0a2pre
