Hi,

We're deploying 4.01 with hibernate and postgresql driver (pg74.215.jdbc3.jar).

After running the application for few hours, we'd get a nullpointer exception as shown in the trace below. Restarting the app server solved the problem but only very temporarily... we've searched a few forums but couldn't find anything similar. Any clues on how we might resolve this? Thanks!
