This happens a lot with clients which use NAT, dynamic IP assignment or which has a 2^32 * 10^-3 seconds upper bound on their uptime. There is no detectable increase in network trafic because of this: two minimal TCP packets every two hours for a live TCP connection. Many servers already enable keepalives themselves.
