JBoss Messaging interaction between separate clusters in JBoss EAP 5.1.1 or 5.1.2

Issue

• Why does nodeA try to send data to nodeB and nodeC on port 7900? They are not in the same cluster as nodeA.

• The following error occurs, where the node listed is in a different cluster

  ERROR [org.jgroups.blocks.ConnectionTable] failed sending data to x.x.x.x:7900: java.net.SocketException: Socket closed
