Zope 2.7.6b3, ZEO, 
Python 2.4.1 (yes, I know it is not yet official but ...
ZEO runs on the same machine but is accessed through an internal network
ZMYSQLDA 2.0.9
MySQL-1.1.7

I have seen several Lock problems and a couple of storage error problems
as I upgrade our system.  Anyone seen anything like this?  

Andy-- I'm guessing this is MySQL related.  I did not upgrade from my 
MySQLdb from 1.1.7.  Should I have?  from cvs? or is there a later 
release?
