I've seen this even for cheap NAT boxes that time-out the NAT mapping
after 10 minutes or so of not seeing a packet. Adding the following to
/etc/ssh/sshd_config fixed that problem, along with cleaning up any
idle connections that are related to a machine just dropping off the
net without first exiting sshd.
ClientAliveInterval 60
ClientAliveCountMax 30
