I have single_parent_bypass on, inside_firewall set and my firewall
configured as parent no-query default.

I see this almost every weekday, for spells of 80 seconds, surrounded by
TCP connection failed/succeeded messages in cache.log. It doesn't
necessarily correspond to times of peak load on either machine - in fact
it's often late at night as well as lunchtimes.

I have amended peerCheckConnectStart() in my neighbors.c to say
eventAdd("peerCheckConnect", peerCheckConnect, p, 1);
so it will only be down for 1 second if this is a transitory thing, as
well as changing the error message in proto.c. The subsequent checks in
peerCheckConnectDone() are unaffected; I just want the first one to
happen immediately.

I also changed the value but this didn't work. It may have ameliorated
problem though.
