I see the same problem on a PIII/300 running 1.5B.

No, only, aborts.

I have not seen full stop of all transmission.

The machine is neither an NFS server nor client, so I guess the
problem is not restricted to NFS. I see about 10 transmit aborts per
hour, relatively evenly distributed. Loading the interface via 'ping
-s 1500 -f' does not appear to change to pattern.
