[comp.protocols.nfs] NFS over PCRoute

Has anyone out there had any problems running NFS over PCRoute?

I know that the folks at Northwestern University (in particular
Vance  morrison@accuvax.nwu.edu) are very happy with their SUN NFS
over PCRoute, so long as they use 4K packets.  I too have set my NFS
packet sizes down  to anything between 1 and 4K, but have
encountered several problems during copies of large (1MB) files
across NFS mounts.

Initially I was using the packet driver version of PCRoute, with
the Version 7.x packet driver for NE1000 ethernet boards.  During
large transfers my local host would suddenly start complaining that
the remote host was not responding.  I would then discover that the
PCRouter had hung....dead.  It was not even possible to reboot it
with Ctrl-Alt-Del, only a hardware reset would suffice.  I naturally
suspected the packet drivers (due to glowing reviews fo PCRoute with
WD8003E boards and no packet drivers).  However, No such problems
occur with NFS xfers on a local Ethernet string (ie no router), but
by the same token, ftp'ing across the router with any size file works
just fine.

Since changing to WD8003E's in my Router, the router no longer
hangs, but I still crash NFS, and in fact yesterday wumped my host
entirely with a Kernel Panic.  OK, so it is probably NFS's fault,
but why only through PCROute?

The router is a 12MHz AT (soon to be a 16/20MHz AT) so processor
speed should not be a problem (NWU us XT's).

Thanks for any help.
