We have 2 jboss server running in the cluster. Messaging is also configured with clustered queues. At one moment we had a database crash. Database was recovered in 5 minutes and connections from jboss were reestablished . All applications works OK, new messages processed correctly. The problem is with the messages processed during the crash time. JMS could not commit them and couldn't rollback at the time. After reestablishing of the connection this messages are not redelivered anymore. The only way to get those message delivered is to restart jboss servers. This is strange problem which we never experienced with old jboss-jms implementation. I tried to open jira task for it but it was closed :( http://jira.jboss.com/jira/browse/JBMESSAGING-1073 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4085506#...
