- From a quick glance at these settings, they all seem reasonable. I'm not
expert on Tomcat clustering, though. If you don't hear anything for a
day or two, try bumping the topic to see if someone else can comment.
You don't have any weird multicast configuration on the NIC do you? Are
you sure that all your network infrastructure is capable of doing
multicast in the way you expect? It's possible that you have a stupid
router or switch that just broadcasts multicast messages instead of
properly sending them.

I'm not sure what the above is supposed to prove... neither the IP
addresses nor the "id" from that log message matches what you have in
your staging configuration. How do you know there's crosstalk?
