outbound request. The usual cause of bogus replies is a misconfigured
piece of networking equipment somewhere between your server and the
other server.
For example, an overloaded router might be overzealously duplicating
packets, thinking they haven't reached the next hop, when in fact
they have. It might even continue the problem by generating enough
traffic, with enough returning traffic (as the next router over tells
it to shut up) that it continues to be overloaded and confused.
Or, the switch connected to one server or the other may be
malfunctioning, doing basically the same thing.
We've seen customers with both scenarios. In one case, the problem
was solved by putting a simple hub between a Mac server and a Cisco
switch. In another case, power-cycling a router solved it.
