This is why we disable overcommit. :-)

Hi,

I already saw that problem on our master. The scheduler, SGE, runs out of memory and OOM decided to kill it:

Dec 1 15:01:07 cluster1 kernel: Out of memory: Kill process 7963 (sge_qmaster) score 948 or sacrifice child

I resolved that issue by disabling "schedd_job_info" in SGE with "qconf -msconf".

However, this setting gives significant informations about our jobs.

How should I adjust OOM killer ? Sould I set

|vm.overcommit_memory = 2
|

?

Best regards,

Rémy
