Concurrent startup of many channels doesn't	stabilize

                 Key: JGRP-770
                 URL: http://jira.jboss.com/jira/browse/JGRP-770
             Project: JGroups
          Issue Type: Bug
            Reporter: Bela Ban
         Assigned To: Vladimir Blagojevic
             Fix For: 2.6.3, 2.7


[Brian Goose]

Jgroups 2.6.2, jdk1.6u4, and OS "Linux bubba 2.6.24-16-generic #1 SMP
Thu Apr 10 13:23:42 UTC 2008 i686 GNU/Linux"

I have 8 machines that all join a channel when they startup.  Usually,
they eventually merge into one view with 8 machines in it, but sometimes
I end up with one view of 7 members and one view of 1 member.  It never
merges, even after waiting for an hour or two.

I've created a unit test that demonstrates this problem while using the
flush-udp stack.  About 20% of the time the views will never merge into
one big view, but instead stays as two separate views, continually
trying to merge and failing.  Do I have something set up wrong here?
Should this test work reliably?

I'm running with these java switches:
	-ea
	-Djava.net.preferIPv4Stack=true
	
-Dorg.apache.commons.logging.LogFactory=org.apache.commons.logging.impl.
LogFactoryImpl

The test class is attached.
