Ok, let's try again: 1) A topic is created 2) A durable subscriber is created fro the topic 3) A message is sent on the topic 4) The durable subscriber pulls the message from the topic ( receive() ) but don't ack 5) The durable subscriber is closed, subscriber session.unsuscribe(name) is called but an exception is thrown and then the subsciber session is closed. As result of this a message, expired, with DELIVERY_COUNT = 1 will remain on the database forever. Is that normal ? Hope it's clearer, thank you Ivan View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4194593#...
