I don't know why there such message. Where can I get more detail information about it or it is error happen to NIC? It's unlikely that this has anything to do with FreeBSD. It's more likely that a networking problem is causing packets to take multiple routes back at times, thus arriving twice. -- Bill Moran Collaborative Fusion Inc.
