Hi!

We have in our network a Ubuntu server working correctly as a web
server & Linux Terminal Server but, unexpectedly, this machine
disconnects from the network. In this moments, this machine doesn't
response ping but it response with arping (I use Hardping tool [1]
from a Windows machine).

I think it's not a machine problem: It's a network problem. If we
disconnect some seconds some wires in our switch, this machine
responses again.

I heard something about protocol problems when there are to many
network traffic what... I don't know what we can do :-(

Any comment or suggestions ?

Thank you very much,

Is the address static? Or is it DHCP assigned?
Perhaps another device is trying to use the same IP address?
What do the logs on the server say?
