Bug 208341 – compiz and X leak memory when computer idle

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Daniel G 2008-01-31 19:41:58 UTC]

Using compiz 0.6.2-r1,compiz-fusion 0.6.0,xorg-server 1.3.0.0-r4 with latest nvidia-driver 169.09 there appears a memory leak in the compiz and X processes. Unfortunately, both times it happened the kernel killed them with no way for me to debug.
I have set up a crontab to output a simple top output every five minutes to find it.
Attached are an excerpt from /var/log/messages and from the top output.
Can someone tell me the best procedure to make them coredump once this happens automatically?

A few top lines when it starts, X starts eating memory

compiz leaks almost 3g res memory

This is the point where compiz helps X eat up all system memory

/var/log/messages time of error

These are the messages on /var/log/messages when processes fail to get memory.

I have the same problem with an Intel 965gm.

x11-base/xorg-server-1.5.0
x11-drivers/xf86-video-i810-2.4.2-r1
x11-wm/compiz-0.7.6-r2

Please test it with compiz-0.7.8.

I still have the problem, also with Compiz git

Can you please open an upstream bug about this and put the link here?

I suffered alot from memory leaks in the 0.6 versions (even the git versions at the time). 

Right now with xorg-server-1.5.2, compiz 0.7.8 and nvidia-drivers 177.80 all seems better.

Use fusion-icon to start compiz and there select Loose Bindig and Indirect Rendering. These gave me the best FPS.

Compiz has been scrutinized for memory leaks and all found have been fixed. The nvidia drivers on the other hand are notorious for memory leaks and could be part of the issue here. If you seem to be affected by this problem, please make sure to include which driver version you are using as well. It is recommended to use compiz 0.7.4 or greater but again, compiz is not known to leak memory at all. Further, I agree with Jorge Manuel B. S. Vicetto. Please make a report at bugs.freedesktop.org and post the link here.

It seems the latest versions have fixed the memory issues.
If anyone still suffers from the memory issues, please reopen this bug.
