> Attached is a program that creates a durable topic subscription, disconnects, publishes a message, and then re-subscribes.
> When running the program, it completes receives the message sent while the subscriber was disconnected. No surprise there. When running the program a second time, the session.createDurableSubscriber call stalls for a while. Eventually it times out with this message:
> Exception in thread "main" javax.jms.JMSException: Error registering consumer: org.apache.qpid.AMQException: timed out waiting for sync: complete = 4, point = 9 [error code 541: internal error]
> On the server side, this is what I get during a failing run:

> If I go into the web manager and delete the exchanges, queues, and sessions, I can run everything again successfully. I can also get a successful rerun if I bounce the server - which I’ve seen the unit tests also demonstrate. If something happens to the client and it needs to reconnect in a short period of time, it will fail to subscribe until Qpid releases the session.
> Based on this topic name, why would it be exclusive in the first place?
