Thanks for the tip, but changing the TCP start_port (along with changing the partition name) doesn't seem to do the trick... I still see messages along the lines of:

So, I guess I'm still wondering how to properly segment my partition from the other one... any additional suggestions would be greatly appreciated. Thanks, - Nathan PS. The "other one" in this case is another developer's machine - interestingly, one that isn't using the TCP stack at all, just the default UDP stack. And when I don't specify a different partition name on my machine, the two JBoss servers actually do appear to cluster successfully... which is somewhat surprising to me. I wouldn't have thought a TCP based server would accept views from a UDP based server. But anyway. PPS.
