I've been having a similar problem, afaict since I moved my server to
5.2-RELEASE from 4.8-RELEASE and to a EPIA 5000 board (from a Pentium
system).

I've not had a disconnection while I've been actively using the
connection but most connections that are left idle get disconnected
after a while (seems to be around 10 to 15 minutes). This happens
consistently at the moment from my development system which can be
running any of 5.2-RELEASE, Windows 98SE or Windows 2000 and has been
seen to occur on another couple of systems. My suspicions currently lie
with the on-board network adapter on the EPIA board using the vr driver
but I have no direct evidence to support it, other than I don't recall
ever seeing it with my old server.
