[i945gme] Moving pointer over Unity's launcher crashes X and causes Unity to reload

[Vish]

Binary package hint: xserver-xorg-video-intel

This happens very often in Unity session.

All i need to do is to move the pointer rapidly over the unity launcher and everything freezes for a couple of secs.
Then Unity reloads.
But i'm not booted out of the session. Only Unity re-loads

Attaching the gdb while this occured

Ran debugging again, this time for both Xorg and mutter...
Looks like mutter just gets SIGKILL'd ...
Still confused though as to why i dont get logged out of the session.

Do let me know if i need to provide any other debugging

[Albert Damen (albrt)]

CurrentDmesg shows:

[12436.390414] Out of memory: kill process 29463 (mutter) score 157749 or a child
[12436.390430] Killed process 29463 (mutter) vsz:630996kB, anon-rss:13324kB, file-rss:16868kB

So mutter was killed because you ran out of memory. It looks like mutter is using a lot of RAM.
You seem to have 1GB of RAM and no swap space enabled. I suggest you first create some swap space. That should prevent the crash and give you time to find out what is using all your memory.

This might be related to Bug #604777 [massive memory leak when hovering over the quicklists] , but not marking this as a dup yet .

We can probably wait for Bug #604777 to be fixed and check again if there are any X crashes..

The memory leak issue fixed this bug as well , so marking it as a dup of Bug #604777
