Windows Forum / Internet Explorer / General Topics / November 2007horrible IE7 memory leak ?
Is there an IE7 memory leak where browser instances can over time move up into the 20, 40, even 60 MB range ? I just experienced out of memory errors on a 2GB RAM machine with a 3GB max paging file. I have about 20 IE7 instances open. No memory leaks in Internet Explorer. Malware can cause the situation you are experiencing. --- Leonard Grey Errare humanum est > Is there an IE7 memory leak where browser instances can over time move up > into the 20, 40, even 60 MB range ? > > I just experienced out of memory errors on a 2GB RAM machine with a 3GB max > paging file.

In addition, you might run a diagnostics test. http://oca.microsoft.com/en/windiag.asp http://www.memtest86.com/  SignatureGistcheckin > No memory leaks in Internet Explorer.

I have about 20 IE7 instances open. IE7 can soak up as much as 400 to 500MB of memory before stalling. I'm a developer, and we have repeated this for verification on 8+ machines with fresh installs of Windows XP, Service Pack 2 and IE7. Eventually, the browser will no longer open tabs or hyperlinks. I am looking for any posts that list a viable workaround. It is not related to browser helper objects, spyware, malware, or the amount of memory installed in a pc, as we have repeated the errors on machines ranging from 500MB to 4GB of high speed, as well as different boards, processors, memory slot types, etc. EggHeadCafe - .NET Developer Portal of Choice http://www.eggheadcafe.com > IE7 can soak up as much as 400 to 500MB of memory before stalling.

This may not be relevant, but I thought I would mention it in case it would help. There is a maximum number of tabs, but I doubt that you would be hitting that: If you are a heavy user of Tabs (50+) you may start to see problems - new tabs and windows may fail to open, right click may not work, programmes may not start. If you experience this problem you can increase the number of tabs that can be opened by editing the registry. The key to use is: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\SubSystems\Windows DWORD very similar to: %SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows SharedSection=1024,3072,512 Windows=On SubSystemType=Windows ServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3 ServerDll=winsrv:ConServerDllInitialization,2 ProfileControl=Off MaxRequestThreads=16 Change the highlighted 3072 to 4096 or even 5120. > IE7 can soak up as much as 400 to 500MB of memory before stalling.

If it's GDI Objects the only workaround I have found is to close some windows and get that statistic back below 9,000. --- > It is not related to browser helper objects, spyware, malware, or the amount of memory installed in a pc, as we have repeated the > errors on machines ranging from 500MB to 4GB of high speed, as well as different boards, processors, memory slot types, etc. > > EggHeadCafe - .NET Developer Portal of Choice > http://www.eggheadcafe.com > Is there an IE7 memory leak where browser instances can over time move up > into the 20, 40, even 60 MB range ? > > I just experienced out of memory errors on a 2GB RAM machine with a 3GB > max paging file. I have about 20 IE7 instances open. I've seen one of my instances of IE7 bloat to nearly 150MB. I'll check a couple times during the day and just minimize IE7 and it clears all that memory. JT Possibly the webpage. It has been noted some will "eat" as much as 500MB. http://www.microsoft.com/windowsxp/expertzone/chats/transcripts/06_0914_ez_ie.mspx http://public.kitware.com/pipermail/vtkusers/2004-April/073081.html SignatureGistcheckin > > Is there an IE7 memory leak where browser instances can over time move up > > into the 20, 40, even 60 MB range ? [quoted text clipped - 8 lines] > > JT Definitely not the web page. We've tried other browsers with no memory hogging. We have even tried IE5 & IE6 on the same pages with no memory issues. Keep in mind that a typical web page at most has 40-50k in code. Some have 100k+, and BHO's take up some more, but this issue is IE7-centric and the root cauase is in the memory handling of multiple tabs. Still, with poorly developed code, leaks abound. EggHeadCafe - .NET Developer Portal of Choice http://www.eggheadcafe.com how about trying to use TABS instead of separate instances. am not surprised with problems with over 20 windows open. mikeyhsd@comcast.net Is there an IE7 memory leak where browser instances can over time move up into the 20, 40, even 60 MB range ? I just experienced out of memory errors on a 2GB RAM machine with a 3GB max paging file. I have about 20 IE7 instances open. And you are wondering why with 20 instances of Windows open., SignaturePeter Please Reply to Newsgroup for the benefit of others Requests for assistance by email can not and will not be acknowledged. > Is there an IE7 memory leak where browser instances can over time move up > into the 20, 40, even 60 MB range ? > > I just experienced out of memory errors on a 2GB RAM machine with a 3GB max > paging file. I have about 20 IE7 instances open. I've been using IE7 for ages both on XP and Vista and have noticed that if I leave browser windows open for hours at a time, regardless of the number of tabs, the memory will continuously expand until all available memory has been used. My computer is left on 24/7 and I have managed to peg memory usage at up to 700Mb on occasions. Note that I have no add-ons installed beyond a clean install of IE7 on either of my primary machines. I've been trying to pin down this issue for months but no matter what I do, it's always the same. The only way I can clear it is to close the open browser window. > Is there an IE7 memory leak where browser instances can over time move up > into the 20, 40, even 60 MB range ? > > I just experienced out of memory errors on a 2GB RAM machine with a 3GB max > paging file.
