One other puzzling thing. I initially deployed PojoCache-service.xml with the ClusterName as the default, Sample-Cluster. I subsequently changed the name to eLynxCluster in both the servers in my cluster and restarted everything. Now I get a warning message that says: 2007-03-06 21:38:26,980 WARN [org.jgroups.protocols.UDP] discarded message from different group "Sample-Cluster" (our group is "eLynxCluster"). Sender was 172.17.20.122:61905 I am curious how it could even be cognizant of the name 'Sample-Cluster' after I changed all references to it and restarted? Go figure.
