You may want to do traceroutes from the systems that do find the 0.0.0.0
interface. I would bet you have a default route and/or netmask sending the
traffic. You will get those arp messages if you run two different
interfaces on the same system, on the same subnet (not to be confused with
running multiple IP's on an interface.) Arp tries to tie an IP address to
a machine address, but if the reverse routing isn't correct you will see
these error messages.
