RE: Neighbour Table Overflow on NFS Server

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.

Navin,
 The message "neighbour table overflow" is the result of

some

changes to the IP stack software in Linux version 2.2.x +.

This

simply means that you are unable to connect to your NFS
server.  It may be related to the driver, but it may also

be

related to other issues, such as NFS server not running or
incorrectly installed, no physical connectivity to NFS

server,

etc.  Check the configuration of your NFS server and IP
network before diving into the driver.
