[jgroups-users] Some Exception

Hello,

We updated from 4.0.13 to 4.0.19  because of 
https://issues.jboss.org/browse/JGRP-2297

Now theres about a 10% change we run into the Exception posted below.
I currently  don't know if the Cluster/Group is still working after the 
Exception.

Anything known about this as of yet or should i collect more information?

Best regards,
Thorsten Goetzke
