Hi,
Starting a new topic just for visibility.
I am trying to build a jboss cluster and having some issues. I've downloaded fresh
copy of jboss-4.2.2 and deployed on 3 servers. I configured cluster-service.xml and
jboss-web-cluster/META-INF/jboss-service.xml and put udp ip and port in there. Here are
the portions of my xml files:
cluster-service.xml

When i start the servers in cluster, 2 of the servers join the cluster fine but adding
third one creates problem and is very slow during startup and gets halt for some time at:
2008-09-01 13:39:51,150 INFO
[org.jboss.ha.framework.interfaces.HAPartition.DefaultPartition] Number of cluster
members: 3

I didn't deploy any application on the servers, these are just fresh servers. I've
tried the same with jboss-4.0.2 and it works fine on the same network with same clustering
configs.
Is there anything changed in new jboss-4.2.2 for the way jboss servers communicate for
clustering? any network configurations i can check? Please help
Thanks
