Are you sure it's OOM? That's a frequent source of SIGKILLs, but SIGKILL is not exclusive to oomkiller. Maybe something in the container stack (some cgroup resource limiting? would be in line with slowdown at least; or a hard ulimit on cpu time?) or maybe even some "anti virus" thingy ("It's been 0 days since AV ate the database").
