Neighbour Table Overflow on NFS Server

[Chris Hallinan]

Can't say I know exactly what it means (internally to the
kernel/driver) but we ALWAYS get this message when the
Ethernet cable is disconnected.  I would suspect physical
connections: check your cable,hub, etc.  In our experience,
it seems to indicate that the Ethernet driver is incapable
of completing transmit operations.

I may be completely off-base here, but I seem to recall
getting some of
these a long time ago.  At the time I think it was cause by
a lack of a
loopback device and routes.
