[jboss-user] [Clustering/JBoss] - Re: JGroups Multiple Registrations

This looks to be the key to the problem:

[org.jgroups.protocol.PING] down_handler thread for PING was interrupted (in order to be terminated), but is is still alive

Machine1-int was detected as non-responsive and excluded from its group (see http://wiki.jboss.org/wiki/Wiki.jsp?page=FDVersusFD_SOCK for details); when it realized this is tried to stop and restart its JGroups channel in order to rejoin the group.  The above message indicates a problem in stopping the channel, which I believe left a "zombie" channel running causing problems.

Suggest you try upgrading JGroups to the latest compatible release, JGroups 2.4.2.
