This could be a router problem: some routers (Cisco?) decide that a host has died if no traffic has been seen for a long time. Google for "vortex sleepy nic" for some discussion.
I haven't seen any reports of this in a looong time. IIRC it was worked around by pinging some remote host once per minute.
