I just set max length on the queue to something like 1k.

Yes, fully agree with Graham. I do rabbitmqctl queue_purge notifications.* In cron every hour + add policy to remove them after 1 min...

Also double check other queues:
rabbitmqctl list_qeues | awk '{if($2>5)print $0}' or smth like that.

Usually something like ceilometer or other telemetry projects,
or projects like Designate and searchlight that don't always have hooks
into nova or neutron, or custom tooling.

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