OOM is configurable via the proc filesystem via /proc/<pid>/oom_adj .
You can set the processes that you do not want to get killed to a
negative number, if I remember correctly, and that will help to
prevent them from being killed by OOM.
So let's say mysqld pid is 123456, you could
echo -17 > /proc/123456/oom_adj
and then it would be less likely to be selected by OOM to be killed.
