Title:
metadata agent make invalid token requests
Status in neutron:
Invalid
Bug description:
Sporadically the neutron metadata agent seems to return 401 wrapped up in a
404.
For still unknown reasons, the metadata agents creates sporadically invalid
v3 token requests
2016-02-26 13:34:46.486 33371 TRACE neutron.agent.metadata.agent
Unauthorized: {"error": {"message": "The resource could not be
found.", "code": 404, "title": "Not Found"}}
POST /tokens HTTP/1.1

and the response is

and the agent will stop responding with a full stack. At first we thought
this issue would be related to a improper auth_url configuration (see
https://bugs.launchpad.net/openstack-ansible/liberty/+bug/1552394) but the
issue came back.
Interestingly the agent start working once we restart it but the problem
slowly appears once you start putting more workload on it (spinning up
instances)
