Hello!
Situation(short):
Some processes on my machine a quite randomly killed with signal 9 without a visible reason. No out-of-memory, out-swap-space and other stuff is noticed.
Situation(long):
I have a development server with 10 concurrently running Redis(in-memory key-value storage) instances. Redis tries to persist once in a while and quite rarely fails with error: forked for persistence process is killed with signal 9. Server has 24gb of RAM and as a rule no more than 5gb is used, so no out-of-memory is possible. And there is 10gb swap partition.
Monitoring(with Ganglia) is turned on and no OOM for sure.
I've searched /var/log/kern.log but did not find anything useful there.
/proc/sys/vm/overcommit_memory is set to 1
/proc/sys/vm/overcommit_ratio is set to 50(default)
Using Ubuntu 12.04.1 LTS
Any suggestions why this can happen or where to look for the answer would be highly appreciated!
Thanks in advance!
