notifications.info</a> queue?<br>
<br>
Usually something like ceilometer or other telemetry projects,<br>
or projects like Designate and searchlight that don't always have hooks<br>

If nothing is consuming them,. you can either set the ttl on the<br>
RMQ queue [1] to something small (just in case you want to look at them)<br>
or disable them [2]<br>
