yes, a crashing server would probably freeze the client, waiting for it
to acknowledge received packets.
Michael's original message indicated the system did run for a bit before
freezing, but from the above "Bad address" error it seems more like it
never really runs on all servers?

have you tried specifying a multicast port and group address (the
arguments to the ClusterServer c'tor after address)?
Can you run the server(s) under gdb with an active catchpoint for thrown
exceptions?
(gdb) catch throw
That would give the point where the socket exception is being thrown.
Did you try running the testClusterServer/testClusterClient programs in
Multicast mode?
Cheers,
Carsten
