so you’re using Apple’s ssh and you’re asking the Macports-users list to help
you with it?

so, clearly there’s something with a state table that is expiring the
‘non-active’ sessions.
You can probably fix it by doing:
Host *
ServerAliveInterval 300
in your ~/.ssh/config

I would probably hit wireshark / tcpdump first to see what was going on (and
probably confirm that there’s some firewall or NAT device that is causing the
problem).

I personally like to use a newer openssh than Apple ships, but in this case I
don’t think it would fix your problem.
