Bug Description

Binary package hint: xserver-xorg-video-intel

Swap space is claimed, when I use memory intesive applications like VmWare or Gimp with big pictures. It seems that the used swap space is almost never freed again. That leads to an unusable slow system, when more swap space is needed and ultimatly to a kenerl panic (out of memory).

Here is a swap space statistics of today (sysstat sar -S). Swap space usage goes up after the start of VmWare (around 13:10), but does not go down again after stopping VmWare (around 13:20). The last line depicts an empty Gnome Desktop with no (visible) programs running.

Bug 360319 pretty similar - Klaus, take a look and mark yours duplicate if you think it's the same, or say what you think is different to help with troubleshooting?

As a temporary fix, I have added the following memory usage limits to /etc/security/limits.conf

root soft data 30000000
root hard data 60000000

It seems to work well and I can run many intensive X applications like wine and firefox without the intensive memory usage and swapping I experienced until yesterday.

I'm using xserver-xorg-video-intel, version 2:2.8.1-1ubuntu1
