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
