Are you using any virtual IP's / NIC's? If so.. remove all of them (only use the main NIC with one IP), and see if you still have the problem. If not, add one virtual IP / NIC, and see if all is still okay. etc ect.. I think that in my case one of the virtual IP's was causing the problem.
An other thing I did (as backup) was that I made a script pinging the gateway ever 5 minutes.. When it did not get a reply, it did a network restart.. After the network restart the network was working fine again.
btw. I'm now not using Fedora anymore (it's Debian now), and all is working fine with my Dell PowerEdge and it's 16 IP's
