my understanding is that if you are calling stop()/wait() your
intention is to shut down the listener. if you intend on keeping an
active consumer on the queue, you shouldn't be calling either stop()
or wait(), just start.<br>

<div>Thanks for the pointer, I'll look into it. But one
question, by calling stop() and then wait(), does it mean the
application has to call start() again after the wait()? to
process more messages?</div>

for the RPC server </div>
<div>Does it mean there has to be stop() and then wait() there
as well?</div>

Hi Doug,<br>
<br>
I have an app that listens to notifications and used the
info provided in<br>
<a moz-do-not-send="true"
href="http://docs.openstack.org/developer/oslo.messaging/notification_listener.html"
rel="noreferrer" target="_blank">http://docs.openstack.org/developer/oslo.messaging/notification_listener.html</a><br>
<br>
<br>
Basically I create<br>
1. NotificationEndpoints(object):<br>
<a moz-do-not-send="true"
href="https://github.com/openstack/networking-cisco/blob/master/networking_cisco/apps/saf/common/rpc.py#L89"
rel="noreferrer" target="_blank">https://github.com/openstack/networking-cisco/blob/master/networking_cisco/apps/saf/common/rpc.py#L89</a><br>
2. NotifcationListener(object):<br>
<a moz-do-not-send="true"
href="https://github.com/openstack/networking-cisco/blob/master/networking_cisco/apps/saf/common/rpc.py#L100"
rel="noreferrer" target="_blank">https://github.com/openstack/networking-cisco/blob/master/networking_cisco/apps/saf/common/rpc.py#L100</a><br>
3. and call start() and then wait()<br>

the correct usage is to call stop() before wait()[1]. for
reference on how to use listeners, you can see Ceilometer[2]<br>
