Public bug reported:
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.
