[j-nsp] arp logs

Well,

given the amount of information about your configs,
network etc, it's hard make any relevant calls.

The issue could be a duplicate IP address, a HA-setup
fubaring your router, VRRP playing tricks like giving
you unsolicited/gratuitous arps and the like.

Are the MAC-adresses part of that one box? Is that
interface directed towards your own infrastructure
or externally? Any VRRP configured? Are servers using
redundant setups connected to that segment?

Shrug,

	Sven
