Managed Servers hung with blocked threads in the production server.

When a remote server hosting a destination goes down or becomes unresponsive, the JMSConnectionPoller used to test and maintain connections for deployed MDB has to reset and recreate connections. When the disconnection is detected, the JMSConnectionPoller attempts to stop and cleanup the associated sessions. But this stop of the session takes a lot longer while holding lock on the JMSConnectionPoller and other threads that detect the disconnection also attempt to get lock on the same JMSConnectionPoller leading to bottleneck in heavily loaded server instances where multiple threads get blocked and cannot do faster recovery in case of disconnections.
