Hi Tom,

thanks for the tip! it was indeed the oom killer.

Is it wise to disable the oom killer? Or will the server really go down withough postgres doing something about it?

currently I already lowered the shared_memory value a bit..

cheers,
Bert

AFAIK there are only two possible sources of signal 9: a manual kill,
or the Linux kernel's OOM killer.  If it's the latter there should be
a concurrent entry in the kernel logfiles about this.  If you find one,
suggest reading up on how to disable OOM kills, or at least reconfigure
your system to make them less probable.
