We are having a similar situation at Penn State.  It seems that PSC
keeps dropping the routing for multicast traffic.  Our Office of
Telecommunications is working with the Pittsburgh Supercomputing Center
to correct our routing problems.

A good program is trafshow for Linux.  This is a network sniffer that
shows active traffic.  If you have multicast on our network, you
should be able to see it with this tool.
