Hi, There is an identified concern on the $Subject.
We are saving topic messages to durable store to share the messages across the nodes and prevent OOM. Consider following scenario 1. Sub1 >> subscribes to topic1 on MB1 node 2. Sub2 >> subscribes to topic1 on MB1 node 3. Sub3 >> subscribes to topic1 on MB1 node Sub1 closes. We cannot delete messages as messages are shared by all subscribers for topic1 (Sub2 and Sub3 are still alive) Now Sub4 >> subscribes to topic1 on MB1 node It will get above mentioned messages which we did not delete (we just send message to all relevant subs on the node). But as per topic behavior this should not happen. What would be possible solutions for this? In MB 2.2.0, we did not get this problem as messages were fire-and-forget (without considering acks, but in MB 3.0.0 we consider acks for topic messages). What would be the possible solutions?
