When I attempt to use a TCP "representative stream" (either as a file or
STDIN) with Iperf 1.6.3, the client will cease sending data after 1-2
seconds and will not recover.  There are no problems doing the same thing
using UDP, nor any problems with a TCP stream originating from memory.  This
also happens with or without parallel streams.

I have 3 machines available for testing: 2 Windows 2000 & 1 FreeBSD v4.7.
This situation occurs regardless of which machine is used as the client or
server and is indifferent to buffer settings (-l).  Any ideas?

My apologies if this question has been asked/answered before; I haven't
encountered an Iperf discussion archive.  Thanks.

-Victor
