Hi,

Got a few freebsd servers and i have noticed quite alot of these 
messages on the console and in the logs.

arp: 10.0.0.100 moved from 00:c0:4f:26:a8:83 to 00:08:c7:3b:67:93 on fxp0
arp: 10.0.0.100 moved from 00:08:c7:3b:67:93 to 00:c0:4f:26:a8:83 on fxp0
arp: 10.0.0.100 moved from 00:c0:4f:26:a8:83 to 00:08:c7:3b:67:93 on fxp0

There is two networks one 10.0.0.0/255.0.0.0 and the second 
192.168.254.0/255.255.255.0

The ip 10.0.0.100 is a proxy/gateway running clarkconnect with dual 
network cards one on 10.0.0.100 and one 192.168.254.100

The messages only seem to show up on the freebsd boxes, there is 3 boxes 
that show these messages.

The first is 10.0.0.222 which has dual cards with the other interface at 
192.168.254.1
The second box only has one card with ip of 10.0.0.60
The third box only one card again with ip 10.0.0.70

These machines are all linked to a 24port 3Com hub... just in case that 
is the problem :(

The question is what is it ? and should i be worried at the amount i am 
getting of them ? and can it be stopped ?

Thanks
Grant.

ps - The first box runs 4.10 and the second and third are running 5.2.1 
There is some linux boxes but they dont show any of the messages.
