Not sure.  MySQL is not my strong point at all.  I spent 4 hours the other
night trying to figure out where my sock file went and why I couldn't create
a new one. (permissions problems)

Average, most of the time is about 995MB..  Max I see about 16-25MB of swap
being used.

Okay, Again, not my strong suit.  Here's the my.cnf file. Anyone see
anything wierd that should be changed?
