Yes, most likely. In the 3 hours or so it took to despool to tape, the
SD->FD TCP connection was dropped for some reason. I am of the opinion
that not all interfaces interpret IEE 802.3az Energy-Efficient Ethernet
in the same way, and when one interface puts its transmitter into sleep
mode, the receiving interface sees it as a dropped connection. Setting a
heartbeat should work, if that is what is happening.
