No, it wasn't, i'm 1000% sure (i was on SSH). Here is the memory usage graph from that system on that time:

The blank part is rebooting into new kernel. MySQL server was killed several times, then i rebooted into previous kernel and problem was gone (not a single MySQL kill). You can see two MySQL kills there on 03:54 and 03:04:30.
