  Using ping -f -s <size> <otherhost> and xosview :), I forced
traffic at various rates.  At around 500KB/sec output, things
started getting bad.

  I upgraded the kernel and rebooted, and things look peachy! 
We still get nfsd errors when the machine is doing 700KB/sec
output pings, but that's to be expected since there's no
bandwidth available on 10Mb Ethernet.  And the machine/nfs
recovers instantly once the ping flood is stopped.

  Thanks a lot!  It's weird that this hasn't bitten us in the
last 4 months.
