DB errors

I'm seeing a lot of php fatal db errors in my phpwiki-1.4.0:

http://sourceforge.net/tracker/?func=detail&aid=3498728&group_id=6121&atid=106121

I'm using the mysql backend.  Is that the best one, or should I switch
to something else, and would that help with this?

I'm also running on a vps now ith limited ram, and running mysql eats up
quite a bit.  I'd like to go to a smaller db solution if possible.

Thanks,
P.
