Grepping the neutron-server logs - a good restart has:

2017-10-24 12:47:27.017 20832 DEBUG neutron.plugins.ml2.drivers.l2pop.rpc [req-ee78be7a-5150-4884-9650-8533eda08e3c - - - - -] Notify l2population agent juju-8ac9b5-pike-gnocchi-testing-17 at q-agent-notifier the message add_fdb_entries with {u'2dfaf721-4af8-44a5-ac25-37e882838b40': {'ports': {u'10.5.0.48': [('00:00:00:00:00:00', '0.0.0.0'), PortInfo(mac_address=u'fa:16:3e:27:ec:71', ip_address=u'192.168.21.11')], u'10.5.0.29': [('00:00:00:00:00:00', '0.0.0.0'), PortInfo(mac_address=u'fa:16:3e:5c:44:6e', ip_address=u'192.168.21.9')], u'10.5.0.28': [('00:00:00:00:00:00', '0.0.0.0'), PortInfo(mac_address=u'fa:16:3e:46:4a:3a', ip_address=u'192.168.21.8')]}, 'network_type': u'gre', 'segment_id': 5}} _notification_host /usr/lib/python2.7/dist-packages/neutron/plugins/ml2/drivers/l2pop/rpc.py:57

whereas once an agent gets into the state where the flows are not reconfigured, I don't see that type of message again.
