I get the following error in my OpenStack Juno installation (one-node) on Ubuntu 14.04:

What maybe happening is the order in which services are started on your system. Since you are running an all in one system and after reboot if the meta-data comes up first and rabbit is not fully up then this can happen.

Since it works under normal conditions I think its safe to ignore!!!!

Looks like meta data agent can't connect to rabbitmq. If you look its says connecting 4 times and then gives up.

Neutron meta-data agent will use the rabbitmq settings in neutron.conf to connect to the message bus.

Is rabbitmq running on os-controller.bui.materna.com?

Did you provide the correct user name and password in to rabbit in neutron.conf?

I can see it in the RabbitMQ Management Plugin that neutron has a valid connection to the server. The credentials are correct and the server is up and running on the specified host. You can see it in the log file that the error occurs 3 minutes after a successful connect.

Can you run neutron agent-list and paste output .

How often do you see this error? Only after restart?

It would interesting if you can log in to the rabbitmq management web ui and see if there are message waiting for neutron meta-data agent.

It seems to be occur only after system restart. When I just restart the metadata-agent service, the error does not appear. I enabled the rabbitmq-tracing, but I am unfamiliar how to use it properly. The tracing must be activated directly after system restart.
