One Topic blocked after failover in HornetQ

Issue

• We are running a 2-node JBoss cluster with external JMS. The JMS is implemented by two JBoss instances driving HornetQ in live/backup configuration with replication.

• During a performance test on the weekend we had a failover from the JMS live server to the backup server. Failover succeeded with the exception of one Topic, which seems to "hang" afterwards: - Applications failed to send messages on this topic - The CLI hanged when the runtime information was queried. All other topics were fully operational.

• Could you please check what might have caused the problem with the topic. I will attach thread dumps of the JMS backup instance, server logs from both JMS instances and the configuration.

• The topic which was affected is used by external clients. These are connected via the RemoteConnectionFactory. Are there similar parameters I can use on normal connection factories ?
