What is strange is there is nothing prior to the drop off that would be an
impetus for congestion (no high BW utilization or packet loss).

Just because there wasn't any congestion reason that *you* could see where you
hat your instrumentation doesn't mean there's 100% congestion free end-to-end.
(Feel free to hit delete if you actually *do* have instrumentation looking
both directions on every segment involved).

Who knows, maybe a few packets got corrupted on the wire, and the TCP chucksum
actually caught it and dropped the offending packets.
