AS HEAD is using JGroups 2.4.beta, which doesn't interoperate with the 2.2.7 version used in 4.0.x.  Presumably someone was running a 4.0.x instance of the AS.
 
To make the error go away, I have changed the port used by the JGroups multiplexer in HEAD to not match any of those used in 4.0.x. The clustered services now all use the multiplexer.
 
It's a good practice to start your AS instance with the -u switch, to give yourself your own multicast address so you don't unintentionally form a cluster with someone else.  But, there are a couple problems that make this not a perfect solution:
 
1) JVM or OS bug on Linux: http://wiki.jboss.org/wiki/Wiki.jsp?page=PromiscuousTraffic
2) Right now the value of the -u switch isn't picked up by the multiplexer; that's something we need to take care of.

Subject: [JBoss-dev] problem starting JBoss AS 5.0.0 Beta in qa-lab

Hello,
 I've got the following problem to start the AS 5.0 beta in qa-lab (JBoss AS 4_0_3_SP1 works fine):
 
[jkijanowski@dev03 bin]$ env|grep IP

MYTESTIPS=10.64.9.15 10.64.9.16 10.64.9.17 10.64.9.18
[jkijanowski@dev03 bin]$ ./run.sh -c all -b $MYTESTIP_1

and it continues until I stop the server. No such problem on my laptop. This issue doesn't prevent me from running tests.
 
P.S.
IP 10.664.48.180 is assigned in /opt/assigend-ips two times:
