Hi all, I'm working on issue GTNPORTAL-2258.

I configure Gatein cluster mode follow by document of gatein (https://docs.jboss.org/author/display/GTNPORTAL35/Clustering+configuration).

When i start gatein with command: 

    $ ./bin/standalone.sh --server-config=standalone-ha.xml -Djboss.node.name=node1 -b 192.168.210.101 -u 2.439.232.2 -Djboss.bind.address.management=192.168.210.101

I can't understand param "-u 239.23.42.2", i see that's multicast IP, but how can i get this ip in my network.

GateIn/JBoss clustering is using JGroups library for cluster communication, which is by default using UDP protocol with multicast. So you just need to have support for multicast in your OS and network. See for example http://en.wikipedia.org/wiki/Multicast_address for more info. For parameter "-u" you need to use multicast IP address (something from 224.0.0.0 to 239.255.255.255). I am seeing that you have invalid address 2.439.232.2 in your first command. Address 239.23.42.2 should be ok. Could you double-check and test again?

When i remove this param and use default of jbossAS and it work with gatein 3.5.x But in 3.6.x and master branch, i always meet exception.

I recommend to always specify "-u" address and choose some 'random' address from the range when you test clustering. When you use default 230.0.0.4, you have quite big chance that your cluster will communicate with someone else on same network who is also testing clustering. And this is usually something, which you don't want and second person as well :-)

Is there anybody know how to fix this bug?
