What? what? oh, no, no again ...

[Andreas Boklund]

Hi Pedro!
I have also noticed the "neighborhood table overflow" error when booting
my Scyld cluster (It is not a production cluster, just made it to compare
a few features with MOSIX). I have 3c509-something, cards and as i see it
the error occurs whenever the nodes are sending RARP-requests and the
network is not responding. In my case this means that the switch (Cisco 
catalyst 2900XL) doesnt show the connection as up. 

I have no idea why you are getting the "fatal error: resetting machine in
30 seconds" error, but i think that the 2 errors might be unrelated. Plug
in the 3com cards and connect the nodes through a hub(just for testing),
and if my theory is correct you should not see the "neighborhood table
overflow" anymore. It does not solve your second problem but it might help 
in troubleshooting. 

Best regards.
//Andreas
