I'm on Adelphia cable internet, and I see these messages off and on. Especially after network problems, there'll be a long list of them. Occassionally, I'll see one MAC address that is generating a lot of these messages ... I assume it's some broken Windows machine that can't figure out what IP to use. There is a sysctl that will turn off reporting of this: net.link.ether.inet.log_arp_movements Set it to 0 to stop the logging. -- Bill Moran Potential Technologies http://www.potentialtech.com
