Remember that when you restart one end of a freeswan tunnel, that the other
end will not talk to you until its keylife expires, since it expects only
crypted traffic, and no new connections.
If you have scripts on both sides restarting things, you probably force
the second one to restart a few minutes after the other end restarts.

There are patches to do this differently, look for "Delete/SA patch".
