[jboss-jira] [JBoss JIRA] Closed: (JGRP-620) RpcDispatcher.callRemoteMethods() hangs

[Bela Ban (JIRA)]

     [ http://jira.jboss.com/jira/browse/JGRP-620?page=all ]

Bela Ban closed JGRP-620.
-------------------------

    Resolution: Cannot Reproduce Bug

Note that it is better to use 'null' for the current membership, as the view you pass into callRemoteMethods() may be outdated.
I'm closing this issue for now. If you have a small program that reproduces it, please re-open this case and attach the program.

> RpcDispatcher.callRemoteMethods() hangs, while there is a lot of member churn at the time (4 servers starting into a cluster of 4). 1 of the 4 server starting up is hung with the attached stack trace.
