"The needs of the many must outweigh the needs of the few (or the one)" :)

Debate on the best strategy for an OOM killer will go on forever :)

Thanks.
  i'll try move to a newer kernel to solve this issue.

OOM = out of memory.

The OOM killer is responsible for killing processes when the system is
running out of virtual memory (so the system itself will "stay alive").

(In your case it hit the X server -- which might be considered
suboptimal, with respect to keeping damage to the end user to a
minimum... ;)

The OOM killer is responsible for killing processes when the system is
running out of virtual memory (so the system itself will "stay alive").

(In your case it hit the X server -- which might be considered
suboptimal, with respect to keeping damage to the end user to a
minimum... ;)

Hi Nikita,
Thanks for the hint, but what is an OOM Killer?

This is the /var/log/messages results of the crash moment:

   



 


Any ideas of what can be the cause?
   


There was an OOM Killer - related bug in 2.6.10, I also faced it some time
ago. Now running 2.6.11 with uptime about 40 days and high load, no
problems.

So you should probably upgrade your kernel.
