"Discarded message from different group" warning in JBoss log with TCP clustering

Solution Verified - Updated -

Issue

  • How do I avoid cluster cross talk when using TCP-based clusters?
  • How to avoid overlapping clusters when using TCP-based clusters?
  • In a clustered (TCP) setup of JBoss, we often find the following messages.
[org.jgroups.protocols.TCP] discarded message from different group "OtherPartition" (our group is "MyPartition"). Sender was 192.168.0.1:1234</code>

In later JBoss EAP versions, messages may appear like such:

WARN  [org.jgroups.protocols.TCP] (thread-3) JGRP000012: discarded message from different cluster ee (our cluster is ejb). Sender was 1f277e10-4ef6-6904-4c26-294dbc1f0bdd (received 3 identical messages from 1f277e10-4ef6-6904-4c26-294dbc1f0bdd in the last 115982 ms)
