> 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.
