My first suspicion would be the transceiver/tap. It looks like packets
are being dropped. Does this happen between ALL of you machines or
just one or two? I'd suggest the following simple test:
	
	o Run PUP trace at both hosts and see if all of the packets are
	  being received at the destination.(SET NTIMES TO 20 in the
	  PUP.ECHOUSER call so that an entire trace can be seen at
	  both machines).

	If you have a 3rd party ether trace system, then you could watch
	the entire dialogue and see what is going on.
