Hrmm, are you sure? I see it try to shutdown, then if that doesn't work
it starts sending SIGTERMs to processes. If the processes ignore the
SIGTERM's, it will wait for them to finish which could be hours or
never, unless I manually send a SIGKILL, which does the job, but the
repository usually needs recovery at that point.

I've gotten some of these previously, but not this time. (This machine
has 2GB of RAM so it takes a bit to OOM it).

I don't think shutting down caused this request, this is just what is
failing to shut down.

Its very repeatable, it just takes a few hours and alot of data to get
Apache into this state.
