I am running my application on Jboss 4.0.4.GA and Jboss 4.0.4.c and on both of them on the ManagedConnectionPool MBEAN ConnectionCreatedCount (Keep going up) ConnectionDestroyedCount (Keep going up ) InUseConnectionCount (Only goes up until managed connection error is thrown and application crashes). Other Information ---------------------- - Log file: I see no entry for any connection leak or house keeping message. I can't see any message related to IDLE REMOVERrunning. - I am retrieving the connection using getConnection() only, no user/passwd. This was working fine on jboss-4.0.2 but not since then. - I have two hibernate applications running on this jboss which use same database but are running fine and aren't using JNDI pooling.

I am confused as to why the idle remover is not running and why are the inUseConnections not coming down even when no one is connected to the application for hours. Thanks,Kazam.
