Message left in delivering state when using SSL transport.

Issue

The test environment consisting of 2 node JBoss Messaging cluster, configured to use SSL, with JMS consumers consuming messages from it. Some messages may be transferred (sucked) from one node to the other. It has been found that during the tests sometimes a message or two gets stuck in delivering state for a very long time and no errors were reported. Restarting the node clears the message.
