I'm guessing it didn't recover *because* there were two processes that
couldn't be killed. Responsibility for that falls to the
operating-system. I've seen it most often with faulty drivers or
hardware that's being communicated with/written to. However, see below.

If not, it means the server is hacked or haunted. Something outside PG
issued a kill -9 and the OOM killer is the prime suspect I'd say.
