It only took two days to figure it out, and after reading thre 157193, messages don't get distributed across a cluster if you bind jboss using 0.0.0.0. Anyone know if a bug has been filed for this?
I am bumping this thread because it helped me to configure HornetQ 2.3.0 in JBoss EAP 6.1.0.GA. I had exactly the same issue with messages not distributing between nodes in the cluster. Thanks for this post!
