[jira] [Created] (ARTEMIS-3602) Cluster connection not distribution messages

Tobias Månsson created ARTEMIS-3602:
---------------------------------------

             Summary: Cluster connection not distribution messages
                 Key: ARTEMIS-3602
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-3602
             Project: ActiveMQ Artemis
          Issue Type: Bug
            Reporter: Tobias Månsson


The cluster is set up as a ON_DEMAND cluster with two nodes, were only one node is exposed to the external load-balancer and receiving new connections. This creates a online failover setup by switching over new connections to the other node, before taking down the current for maintenance.

During one deployment, the active broker node was failed over without shutting down the passive node. This left the current connection on the passive node, while new connections were created against the now active one.

If message were sent to the now passive node, they were synchronized correctly to both nodes and to all connections. But if the messages were sent to then now active node (the intended behavior), they were not sent to clients currently connected to the now passive node.

The logs and message counters confirm this, but no cause has been found.
