The server quit without updating PID file - mysql

Question

I tried running optimize on one of my tables, and when I did the server crashed. Now when I try to restart it, I get this error:
The server quit without updating PID file (/usr/local/mysql/data/Diskise.pid).
Then when I look at the error log to help me see what happened, I don't really understand it. What can I do to get my server back up?

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.
key_buffer_size=8388608
read_buffer_size=131072
max_used_connections=0
max_threads=151
thread_count=0
connection_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 67592 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
