We copied latest jgroups jars. I am sure, we have proper configuration in 
cluster-service.xml and tc5-cluster-service.xml. But, we are seeing the 
following errors. I assume, this is happening when one server get shunned and 
try to come back.


The cluster is perfectly fine for 4 - 5 hours. After that, the cluster has the 
following WARN, ERROR and Exceptions:

Server1:
