Hi,
we have a problem with our contrail setup:
it looks like contrail doesn't work off the rabbitmq queues:
root@juju-machine-3-lxc-23:~# rabbitmqctl list_queues -p contrail
Listing queues ...

...done.
In the contrail-svc-monitor-stdout.log I see python errors:

Has anyone an idea what the problem could be?
We use contrail 3.0.2 deployed with the canonical juju charms from Robert Ayres.
