Did you ever find a solution to this problem? I am trying to setup a 2 machine cluster and have received the same error. I started a thread at http://forums.java.net/jive/thread.jspa?threadID=32849&tstart=0 though I have yet to receive any replies. I'm working on two machines with fresh installs of Fedora 7. Please let me know if you have had any success working around this.
