I had a similar issue. The problem was with the multicast routing. I was using two NICs on each node...one public (eth0) and one private (eth1), with the default gateway going out eth0.

The route for the multicast (224.x.x.x) was going out the default
gateway and not reaching the other machine.  By putting in a fixed route
in for multicast:

    route add -net 224.0.0.0/8 dev eth1

it all started working.  This was my fix, it may not work for you.
Also, I use the CVS code from http://sources.redhat.com/cluster and
not the source RPMs from where you specified.

Yeap, both boxes have two NICs. eth0 is public, and eth1 is private (192.168.2.x). I tried adding the route, and that didn't fix it. I've also tried disabling the private NIC before and running with one public NIC, and that didn't fix it either. One other interesting thing I noticed...when I run cman_tool join on nodeA, netstat shows ccsd trying to do this:
