BGP session initially comes up but after learning all the routes from the peer ODL stops sending BGP keepalives. So the peer drops the session with code 4 (hold timer expired). Then when BGP comes back up it gets stuck in "OpenConfirm" at the other end (as no keepalive received from ODL).
ODL claims it is sending keepalives:

but from a tcpdump and from debug on the router that's clearly not the case.
