I have a problem when use 'notification listener' oslo-message for HA Openstack.
It raise 'oslo_messaging.exceptions.MessageDeliveryFailure: Unable to connect to AMQP server on
172.16.4.125:5672 after inf tries: Exchange.declare: (406) PRECONDITION_FAILED - inequivalent arg 'durable' for exchange 'nova' in vhost '/': received 'false' but current is 'true''.
How can i fix this?. I think settings default in my program set 'durable' is False so it can't listen RabbitMQ Openstack?
This is my nova.conf
http://paste.openstack.org/show/738813/
And section [oslo_messaging_rabbit]
[oslo_messaging_rabbit]
rabbit_ha_queues = true
rabbit_retry_interval = 1
rabbit_retry_backoff = 2
amqp_durable_queues= true
