Hello Assaf, I am still having trouble understanding your scenario: "assaf49" wrote : | | Scenario Clarified: | 1) Producer sends Message A. | 2) BEFORE Message A is recieved, some Connection failure occurs on the Listeners side. Note that the client does NOT crash, it's just a 'small' connection problem. | 3) JBM is trying to recover the Listeners Connection failure. | I'm not sure I understand what you mean by "JBM is trying to recover...". Are you using a clustered connection? If so, JBM will attempt to failover to a new server if it detects the connection is lost. Maybe you have coded your own exception listener and reconnect logic? anonymous wrote : | 4) Producer sends Message B (while JBM is still in process of trying to recover the Connection failure). | 5) JBM manages to recover the Connection failure (as to your question, remember that there is no need to Recreate the listeners because they never crashed in the first place). | Not sure what you mean by "JBM manages to recover..." anonymous wrote : | 6) Redelivery mechanism redelivers Message B to Client (can this happen?) | No redelivery mechanism should kick in unless you have coded your own exception listener and have implemented some retry logic. anonymous wrote : | 7) Redelivery mechanism redelivers Message A to Client (order is lost and the Listener is not even aware of it) | | Order should never be lost.
