ARP stands for Address Resolution Protocol.

It's used to relate a network address {logical address - EG 10.20.20.20}
to a MAC {Physical address - EG 00C04FADBA60} for routing/communications
purposes.

That error message indicates you have a misconfigured LAN card/network
address/router address or something in your network setup is wrong.

I've seen it before, but I can't for the life of me remember what exactly
is the cause.

Check your LAN card setup - IP address, network address, router address,
broadcast address, netmask  etc - it could be you have your default router
set to the same as your LAN card, which means when the routing protocol
tries to find out the physical address of your default router, it's asking
for its own address.
