hi, i have a problem in a server, from some time ago, the console shows
this strange message (strange means i can't imagine what's its scope):

arp: ***.***.161.65 moved from 00:50:0b:6c:a4:1a to 00:00:0c:07:ac:1f on
fxp1
arp: ***.***.161.65 moved from 00:00:0c:07:ac:1f to 00:50:0b:6c:a4:1a on
fxp1

the server IP address is ***.***.161.107 (netmask /25) and
***.***.161.65 is tha IP address of the gateway (a Cisco Catalyst 6500)

it's doing so every 30 minutes, but varies, it can be one or two hours
between MAC changes... 

this machine has not been updated from two months, it was working
normally, IPv6 services are working (it routes packets between
interfaces) but networking on the IPv4 address doesn't work (neither
sshd nor pinging other hosts)

any ideas???

thanks in advance,

toni
