Hi,
I have been having an issue where the database portion of my application
becomes unusable after a commit fails. I am using hibernate 3.2.4 and
derby 10.2.2. The following exception is thrown. The database call
that causes this exception has been called numerous times before during
the running of this application and occasionally this exception is
thrown. The database call is a simple update.

After this exception is thrown hibernate tries to release it's
connection back to the connection pool and continue on. However another
exception is throw for each subsequent call to hibernate (and therefore
derby).

Any advice on why / how the initial exception could be cause would be
appreciated.
Thanks,
