OOM-Killer called every now and then..
- by SpyrosP
Hello there, i have a dedicated server where i've installed apache2, as well as Rails Passenger. Although i have 2GBs of RAM and most times about 1,5GB is free, there are some random times when i lose ssh and generic connectivity because oom-killer is killing processes.
I suppose there is a memory leak but i cannot find out where it comes from. oom-killer kills apache2, mysql, passenger, whatever.
Yesterday, i did a "cat syslog | grep -c oom-killer" and got 57 occurences !
It seems that something seriously destroys the memory. Once i reboot, everything comes back to normal. I suspect that it can be related to Passenger, but i'm still trying to figure it out.
Can you think of anything else, or do you have anything to suggest that will make the leak identification procedure easier ? (i was even thinking of writing a bash script, to be run with cron for like every 5 minutes).
