Right... if the connection is long lived, there was a handshake, it just
happened before Bro started.

I'm not sure about the Bro side, but you could probably turn off keepalives on
the load balancer.  It also might have an option somewhere called 'maximum
number of requests' that might be a high number like 5000, you could try
lowering that a bunch, which would cause a handshake to happen frequently
enough to keep Bro happy.
