I am pretty sure you are the first person trying to run multiple 
independent rabbit clusters on the same machine.

To do that you'll probably have to change some settings for each of the 
clusters. See http://www.erlang.org/doc/man/epmd.html

ERL_EPMD_PORT
This environment variable can contain the port number epmd will use. The 
default port will work fine in most cases. A different port can be 
specified to allow several instances of epmd, representing independent 
clusters of nodes, to co-exist on the same host. All nodes in a cluster 
must use the same epmd port number.


Giving each cluster a different erlang cookie might be sufficient too, 
though I haven't tried that.

Matthias.
