I re-read your log again.  A server name being thrown out could be the j-groups 
dropping you and re-adding you.  Do you see a message indicating a new generation of 
the cluster being formed?

Again, I am thinking that the multi-cast messages are getting dropped due to traffic 
conditions.  Multi-casting could cause some gyrations.  You could open up the grace 
window by changing some of the parameters in cluster-service.xml.  You could increase 
the number of attempts from 3 to 5.  You could also increase the reply time timeout 
(it's possible the 2 seconds default is TOO slow for the load running on your server). 
 You might have to soften the timeout to more like 5 seconds.  Lastly, if the message 
delivery is really nasty, you could use QOS or some other means to give your J-Groups 
traffic priority.  Failing that, you might want to consider changing the J-Groups 
traffic to TCP/IP unicast messages.  Although this would be more cumbersome, the 
deliver of unicast IP traffic is almost guaranteed (as compared to Multicasts).
