Hi Markus, https://jira.jboss.org/jira/browse/JBMESSAGING-1726 About the delivery stop, I think the problem is in ChannelSupport.InMemoryCallback.afterCommit(): promptDelivery = (promptDelivery || monitor.messageCompleted(ref)); This line has its flaw, you can see if promptDelivery is true, the second expression won't be evaluated (i.e. monitor.messageCompleted(ref)). But it must be executed in order to unregister a finished message. so https://jira.jboss.org/jira/browse/JBMESSAGING-1727 Also I think you are right in that the paged references won't need registered (save memory). We can only registered at loading their loading time. But this doesn't affect functionality. https://jira.jboss.org/jira/browse/JBMESSAGING-1728 View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4252338#...
