[jboss-jira] [JBoss JIRA] Commented: (JGRP-1343) JGroups 2.6.2 hangs during JChannel.connect

[Bela Ban (JIRA)]

    [ https://issues.jboss.org/browse/JGRP-1343?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12612631#comment-12612631 ] 

Bela Ban commented on JGRP-1343:
--------------------------------

2.6.2 is old, I suggest try with at least 2.6.15 (downloadable from SourceForge). 
I'm going to close this. If you can reproduce the issue, please re-open the case and add the exact steps (and the program used) to reproduce it.
You can also try a later version (branch on GitHub is Branch_JGroups_2_6), but you have to build it yourself.

> 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.
