Hi Manik,
Thanks for the reply...here is my info:
1) yes, the Java client is using the same JGroups stack as the appserver (essentially just the jbossall-client.jar, jbosscache-core.jar and jgroups.jar files found in the JBoss server distribution). This is all under JBoss 5.1.0.GA.
Also, if it helps, I'm running my client application with the following system properties to help it try to join the JGroups channel (though running with or without these properties doesn't seem to make any difference for me):
| -Djgroups.udp.mcast_addr=228.1.2.3 -Djgroups.mping.mcast_port=39472 -Djgroups.udp.mcast_port=34972 -Djgroups.bind_addr=10.1.0.22
|
2) here's the thread dump:
