No, it wasn't, i'm 1000% sure (i was on SSH). Here is the memory usage graph from that system on that time: http://www.watchdog.sk/lkml/memory.png The blank part is rebooting into new kernel.

You can see two MySQL kills there on 03:54 and 03:04:30. > >> Maybe i should mention that MySQL server has it's own cgroup (called >> 'mysql') but with no limits to any resources. > >Where is that group in the hierarchy?
