[Linux-cluster] Cannot join two nodes together

I have two nodes on the same subnet, can ping each other, are both
alive, both are members of a two-node cluster.  When I start cman on
both nodes at the same time it says "X not a cluster member after 60 sec
post_join_delay".  The output of clustat shows that the other node is
"Offline" and the first node is "Online, local".  The nodes are fencing
each other and powering each other off.  


Please help determine why I cannot get these nodes to join. Below is
some information from my systems. RedHat Support is not getting






Node1: bplmft11

Node2: bplmft12


uname -a -> Linux bplmft11 2.6.18-8.1.10.el5 #1 SMP Thu Aug 30 20:43:28

/etc/cluster/cluster.conf file (with the fencing levels removed):
