JBOSS 4.0.4.GA clustering in Linux

[girijasahoo]

I have installed two JBoss 4.0.4.GA in two Linux server. Started the two server by using sh run.sh -c all. But two server automatically not detecting each other for clustering. But the same is working in Windows environment. Can anybody help me.

Thanks in advance.

I'm having a similar basic problem with the 4.2.1 GA. I upgraded from 4.0.2, where clustering worked fine. With 4.2.1 GA the servers even don't start up, but seem to hang somewhere in the JGroups initialisation. I'm using Suse Linux 10.2, and tried it both with JDKs 5 and 6. If anyone has come accross a similar problem and has any hints, this would be appreciated.

You send me the run.sh?

It's the default run.sh:
