Public bug reported:

Neutron server keeps sending notification messages (e.g. port
create/update/delete, network create/update/delete etc. ) to all dhcp-
agents including inactive ones. This creates a problem that after
running for a long time there can be huge amount of pending messages in
rabbitmq for those inactive nodes.

The consequence is, when those inactive nodes are back to active, it
will stuck if there are too many messages to handle (depends on how long
the agent has stayed in inactive state), and sometime failed to start
properly due to errors like:

ERROR neutron.openstack.common.rpc.common [-] Failed to consume message
from queue: [Errno 104] Connection reset by peer

So the proposal is to send notifications to active nodes only.
