Hi Ray,
Thanks for answering.

# sysctl -a | grep keep
net.inet.ip.keepfaith: 0
net.inet.ip.fw.dyn_keepalive: 1
net.inet.tcp.keepidle: 7200000
net.inet.tcp.keepintvl: 75000
net.inet.tcp.keepinit: 75000
net.inet.tcp.always_keepalive: 1
net.inet6.ip6.keepfaith: 0

I see that keepalive starts after 2 hours(?) (net.inet.tcp.keepidle), 
but what would disable it? I guess always_keepalive=0.
