Comment 4 for bug 1572320

On the assumption that you are running multiple nova-cloud-controller service units, I need to understand which of the HA options you are using for nova-consoleauth, as I think its what the charm is doing in terms of managing the process via upstart that is causing the problem; specifically:

  single-nova-consoleauth
  console-access-protocol

would be useful configuration options to see please (I'm assuming that you are also using the hacluster charm for HA).
