----------------------------------------

Trying to get some time to investigate this. Maybe tonight?

Do you see anything suspicious in your logs? Maybe something like:

"Error occurred during execution of ExpirationMonitor TimerTask"

> I have frequent trouble with my database pool to an AS/400.  The database is taken down every night for backup, and at least once a week the connection pool is unusable after the database comes back up.  Restarting the connection pool makes everything work again. 
> We are new to Geronimo/WAS-CE -- just this one app on one server -- so I don't have anything to compare to.  However, we have had this same issue with a couple 1.x/1.1.x versions before we upgraded to v2.  Also, there are several WebSphere (full WAS, not WAS-CE) apps that do not have this trouble.
> Configuration Info
> Driver: JTOpen v6.1 (com.ibm.as400.access.AS400JDBCDriver)
> Pool Min Size: 0
> Pool Max Size: 100
> Blocking Timeout: 5000
> Idle Timeout: 15
