"Discarded message from different group" warning in JBoss EAP logs
Issue
- I am seeing a few messages in the server logs relating to clustering that seem to suggest a cluster configuration issue / A cluster not being fully isolated from each other.
WARN [org.jgroups.protocols.UDP] discarded message from different group "Tomcat-otherPartition" (our group is "Tomcat-myPartition"). Sender was 1.2.3.4:12345 - How to stop the partition name warning messages?
- I have tried to isolate the nodes in a cluster using the -u and -g option but I'm still getting cross-talk between cluster nodes. The cross-talk seems to be coming from the same server. Only one EAP instance is running on the server
