It still occurs with revision 2769, which was the most current one on TRUNK on this Monday and was checked in after JBMESSAGING-982 was closed. In addition there are several differences to the behaviour reported in conjunction with JBMESSAGING-982: 1. It happens not only under heavy load as a race condition, but always. 2. The non-shrinking of the depth counter can be observed immediately and before closing the consumer. As far as I can tell, it is not related and not resolved with the previous issue.
