Resolved. Thanks to all that responded.
The symptoms were due to an external method which runs a program (htmldoc)
that converts html to pdf. The external method uses the "old" subprocess
interface to fire off the process and then wait() for it to complete. To
fix another problem, we had upgr

We had been plagued with a threading error which manifests itself
as an exception reporting "release unreleased lock". At Andy's
suggestion I added code to catch the exception in the appropriate
place in ZMySQLDA --
Here's the code from db.py ---
The code probably should be specific to the

things tonight.
We use a remote ZEO but at the moment Zope and ZEO shar

Chris,
A helpful suggestion. The commit errors I've been seeing have to
do with the intereaction of the ZODB, MySQL, session variables, and
