That's interesting, though as I said earlier I doubt it's the same
problem I'm having.
I'm getting a high incidence (3%) of receive errors, which seems to
vary from one reboot to the next with no apparent pattern. Changing
cables, ports and routers seems to make no difference.
Check components near the ethernet port for signs of damage.
I once worked on a Windows PC running PCNFS. NFS was
failing. I ran the vendor's diagnostics on the network card and
it came up "healthy", but visual inspection of the card revealed
fried components. The PC was connected via very long cables
to a satellite dish, so very likely subject to spikes of induced
current from lightning. A well-built system like the SGI Octanes
is much more robust. I actually saw lightening come in the
corner of the computer room and down across an Octane.
The Octane survived except for the small bulbs in the light
bar which was outside the heavy metal chassis.
I've just bought a new NIC card and will install it before my next
reboot. Hopefully that will fix it.
It could be worth trying diagnostics if you can find them. Usually
they are DOS programs. HP used to have a program to make
bootable DOS USB keys, not there is "Rufus"
