fedora

I have an old server running Fedora 4 that occasionally just stops responding via network for about an hour. This happens 1-2 times a week.

Also no connection from the server itself to any other computer on the network is possible when it happens. The network settings and routes look fine. There are no unusual log messages and no unusual processes running at that time.

If I restart the network or just do an ifconfig eth0 down & ifconfig eth0 up it works fine afterwards.

I know that the server should be updated to a currently supported OS, but that is not really an easy option right now.

Any ideas on how I could diagnose and fix that problem?
