    The box is almost idle - there's definitely no pings going on, and no traceroutes either, also no RIP.

    Could this be caused by a flood of some sort? (like a DoS attack?)

    No, not udp - the only UDP traffic that'd be going on with the box is DNS. The box runs qmail, apache, ssh and that's it. Nothing else - no other ports are open on the machine other than ones for these services, everything else is locked down (syslog's not listening on a network port, mysql isn't etc. etc.).
