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.
