Symptoms

When a JMS application terminates abnormally without closing the message consumer, connection and session, any non-durable subscribers created during the execution of the application will remain associated to the queue.  Subsequent messages enqueued in the queue for new durable subscribers will also be enqueued for the stale subscribers. As this messages are not consumed they cause the queue to grow in size over time generating performance problems for the dequeue operations and admin tasks executed on the queue.
