It's probably that you've hit a weakness with the cluster name hash, 
it's not perfect by any means. Your options are to change one of the 
cluster names so that they hash to different values or (easier) add

<cman cluster_id="XXX/>

to one or both of the cluster.conf files to force a different cluster ID
