When my lady friend logs in over ssh -- you don't often see those words in
that particular order -- her connection times out if it's idle for 10
minutes:

$ time ssh j@www.schemamania.org

Welcome to NetBSD!

Setting debuggin on with -vvv, I get this, which doesn't make anything
clearer to me:

debug1: channel_free: channel 0: client-session, nchannels 1
debug3: channel_free: status: The following connections are open:
  #0 client-session (t4 r0 i0/0 o0/0 fd 4/5)

Question: Did tcp/ip or ssh shut down the session?  Or possibly NAT/ipf?  

I see from the archives that others have had similar problems, but I don't
see any definitive answer.  In case it matters, her /usr/bin/ssh is
provided by FreeBSD 5.0.  

Thanks.
