We have been getting a fair number of people having problems with ganglia tests failing lately. I have not been able to reproduce the problem myself, so I am not sure where the issue is.
Sometimes it breaks because of problems with the /etc/hosts file. Also, what kind of switch are you using? Ganglia likes to (needs to? not sure) use multicast, which is not supported on all switches.
