Open Stack

These errors do line up to the time where it's down.
However, I have no idea what cause apache to seg fault.

These errors probably maybe line up with the failure start?

Here are the recent failures I can find, do these line up with failure
times? This does not seem to be consistent time like suggested with
the cron job.

I'm really not sure what happened with the logs; the 8th rotation
seems to have disappeared and then they get really old.
