Public bug reported: While testing oslo.messaging zmq driver, we came across with the following behavior of neutron: it sends fanout messages to the target <Target topic=q-agent-notifier-network-delete, version=1.0, fanout=True>, although there are no such services. Zmq driver uses redis as a matchmaker for coordination between rpc clients and servers, and each server registers itself in redis so that clients can find it. In our particular case redis has no records associated with the topic q -agent-notifier-network-delete, and our current behavior is to retry (20 seconds at most, 2 seconds between attempts) to get available hosts from redis, and drop the message afterwards. As a result we get failed tests. By the way, if we drop those messages immediately, everything works fine.
