Sometimes things in between the two systems you have control over
cause problems that make these settings not work as you would expect.

I have seen cases where disabling both keep alive message types worked
best in terms of not having the connections get terminated.

ClientAliveInterval  0  # don't send keep alive messages
TCPKeepAlive no  # and no TCP keep alive messages either (default is yes)

Guess it was a firewall issue or some intermittent connectivity
problem, but disabling the those two things made for more stable
sessions.  One downside is that when a connection gets terminated
there is a zombie process left on the server that has to be killed
off.
