I am using a mac. Recently I turned it off and now when I try to bring up the database the service will not start at all. I looked in the localhost.err log file and see that it says something like below: CAN ANYBODY HELP ME!!!

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help diagnose
the problem, but since we have already crashed, something is definitely wrong
and this may fail.
