In addition to routers/switches/firewalls between the FD and SD, I have
also seen the machine running FD cause this issue. For example, if a
relatively weak client machine takes a long time to compress/encrypt a
large file, it is possible that a network device driver with overly
aggressive power management settings thinks there is no activity and
powers down the PHY, even though there is an open socket. I don't know
if that is a bug or a feature. I doubt that is the case with the QNAP
box, but I have seen it with Windows and Mac clients, particularly when
connected with WiFi devices.
