I thought that clients of the clustered queue could connect to whichever node they found first and they would get messages from any partial queue. Is this incorrect?

| In your case it seems it would make more sense for each of your windows servers to consume from different redhat servers since you have one less network round trip.
| I.e. if each windows server is consuming from its own redhat server then JBM just needs to shift the message from redhat server --> windows server.
| If both windows server are consuming from the same redhat server then messages not only have to get from redhat server 1 to windows server 1 and 2, but also from redhat server 2 --> redhat server 1 -> windows server 1 and 2.
| Although it's a sub-optimal topology it should still work - things to check:
| 1) Are the queus deployed as clustered = true?
| 2) Is each node in the cluster seeing each other? Have a look at the console output from jgroups as they start, when you start the second one you should see the first one registering that.
| 3) Make there is an issue with CR release you are using? Have you tried the latest release?
| Hope that helps :)
