getting qpid setup correctly.  I am able to bring up qpid fine on either testbroker1 or testbroker2,
but once a broker is running on one machine I am unable to start qpid on the other.  The error
message is as follows:

That is a known issue. When adding a new member to the cluster, it must 
have an empty store (otherwise the state of the store and the state 
retrieved from the other cluster members will clash).

If you use '--data-dir /path/to/store/data' and ensure that for all but 
the first node of the cluster that is an empty directory then you should 
avoid this issue.

I believe this may already be fixed on trunk, certainly some work has 
been going on to address it.

and 1 public interface).  I am using the dedicated network for the openais multicast.  Both
brokers are in a clustered configuration and are members of the same group.  Everything was
installed from the RHN binaries v1.1.1 (we are jointly testing things with Redhat).
