JGroups 2.6.2 hangs during JChannel.connect
-------------------------------------------

                 Key: JGRP-1343
                 URL: https://issues.jboss.org/browse/JGRP-1343
             Project: JGroups
          Issue Type: Task
    Affects Versions: 2.6.2
         Environment: Linux, cluster
            Reporter: Sandeep T H
            Assignee: Bela Ban


In a cluster having two nodes A & B, A is up and running and when B is started for the first time it sometimes hangs in JChannel.connect.
If we bring down A then B is able to resume and connect. This issue happens randomly but frequently.
Please let us know if we have missed something or need something.
