hi

I'm getting on my freeBSD 7.3 a lot this kind of messages:

arp: 10.10.1.90 moved from 00:06:5a:f7:7a:2b to 00:06:5b:f7:7b:2a on em0

Howto stop them?

Tell those darn kids on 10.10.1.90 to stop using their load balancer.

Either there's some kind of link aggregation (see lagg(4) for the FreeBSD version) happening on multiple NICs on 10.10.1.90; or there are two separate computers on the network trying to use the same IP address.
