Rohit Singh commented on JGRP-2041:
-----------------------------------

Hi Bela,

I am attaching the configuration files that we use for JGroup cluster settings. "jgroups_cluster.properties"

You mentioned that abruptly ending the process on one node could cause this issue, can kill -3 also cause it ?
We generally for kill -3 to collect thread dumps.
Can it also happen because due to network issues one node is not able to communicate with other node ?
