We had a similar problem between our linux server (running on a PC)
and a TS-7200. Anyway, any large file activity would "hang" the NFS.
As NFS is UDP/IP and not TCP/IP our problem was that we had the
TS-7200 board on a 10Mbit hub, while our PC was connected to a 100Mbit
switch (10Mbit unlink between). Because there is not flow control
with UDP/IP the 100Mbit would choke the 10Mbit. If we connected
either node to the same switch and/or hub the problem went away.
Whether it was a flow control problem or not I could not fully
conculude without some serious debugging.
