Comment 1 for bug 1810504

This is very strange issue for me. It looks that it fails in https://github.com/openstack/neutron/blob/master/neutron/services/qos/qos_plugin.py#L102 where there is something like:

    net = network_object.Network.get_object(
        context.get_admin_context(), id=port_res['network_id'])
    if net.qos_policy_id:
        qos_policy = policy_object.QosPolicy.get_network_policy(
            context.get_admin_context(), net.id)

But how it is even possible that there is no network which is configured in port?
From logs it doesn't look like it could be removed in parallel :/
