Can't explain it really well, but the essence of the bug in Oracle was that the tnslistener's connection count wasn't updated "regularly enough" when connections closed, so it could believe that the connection limit had exceeded when the db instance was still happy to accept more connections. As I recall this was a known Oracle issue, and was fixed by increasing the acceptable connection count in Oracle. Can you provide the exact exception from the logs that you hit? Also have you tried turning on connection pool logging to diagnose when actual physical connections are created? Chris
