No, but have you modfied the "testRelay.cpp" code?  I suspect that 
you have changed the destination multicast address to be the same as 
the incoming multicast address.  Don't do this - it will cause 
outgoing multicast packets to get 'looped back' and re-transmitted 
(ad infinitum).

"testRelay" was not intended to be used to relay traffic between two 
different networks using the same multicast address.  (For that, you 
need proper multicast routing - i.e., enabled in the OS.)
