JGroups 2.6.2 hangs during JChannel.connect ------------------------------------------- Key: JGRP-1343 URL: https://issues.jboss.org/browse/JGRP-1343 Project: JGroups Issue Type: Quality Risk 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.
