    [org.jgroups.protocols.pbcast.NAKACK] [mach:port] discarded

    Frank Snedecor Newbie

      Hello, I am running 5 servers running Jboss-4.0.3SP1 with sticky sessions behind a load balancer. Jgroups version 2.2.7 The problem I am seeing is that after some time, the logs start to fill with [org.jgroups.protocols.pbcast.NAKACK] [vrx14:58902] discarded message from non-member vrx15-in:41415. However the console is showing all of them as members as shown below. Currently in this case vrx10 is the coordinator. The only way to fix is to simply adjust the communication ports of the JBOSS clustering services for each UI machine and restart JBOSS. However this bas been decided as being unacceptable. Here is a bunch of ouput from org.jgroups. Any help/advice on resolving this would be greatly appreciated.

      In this output it is showing vrx15 as null.

      I have verified that these are in fact part of the same cluster by going to jmx-console.
