That sounds like you're behind a NAT'ed firewall. Quiet connections
will often go dead (by the firewall) in an hour or less (I've seen 30
minutes on some). My ssh tunnel connections always use a 'ping -i
localhost 600' on the tunnel-setup ssh to keep the connections up.

You may instead try to set the TCP option SO_KEEPALIVE (see 'man
socket') to see if it helps.
