Any help on where to start to fix this would be appreciated.

I'm Running FC5 and FC6 as a mailserver/ftp/mailman and they both seem
to be doing the same thing.

I'm not sure whether you mean "ARP requests" are the problem or whether
you mean the number of them is the problem but ARP requests are normal.
It's how the network discovers the hardware address (eg MAC address)
from the IP address. 1000 per minute seems high to me but then it
depends on your traffic levels.

Along with that, ARP requests are only sent to the local network and not
"the world". They don't survive past a router since, as noted above, their
purpose is to obtain the MAC address equated to an IP address and MAC
addresses are only used on the local subnet.

A network configuration error could explain what you are seeing. However,
without additional information we can't help much.
