Mitaka ironic-conductor error on stop: Cannot switch to MAINLOOP from MAINLOOP

[Matt Fischer]

Using the mitaka packages from trusty/proposed:

ii ironic-api 1:5.1.0-0ubuntu1~cloud0 all Openstack bare metal provisioning service - API
ii ironic-common 1:5.1.0-0ubuntu1~cloud0 all Openstack bare metal provisioning service - daemons
ii ironic-conductor 1:5.1.0-0ubuntu1~cloud0 all Openstack bare metal provisioning service - conductor
ii python-ironic 1:5.1.0-0ubuntu1~cloud0 all Openstack bare metal provisioning service - Python library
ii python-ironic-lib 1.1.0-1~cloud0 all common library used by various Ironic projects - Python 2.7
ii python-ironicclient 1.2.0-0ubuntu1~cloud0 all Client for OpenStack bare metal Service - Python 2.7

I'm not sure what's going on but conductor is throwing this when stopping:

However it is actually no longer running:

What version of Oslo.service are you running? http://lists.openstack.org/pipermail/openstack-dev/2016-February/086978.html appears to indicate it's a problem with an incompatible version of Oslo.service.

I've marked this bug "incomplete" pending that information, as until we know it we can't address your problem.

Thanks!

This was from work on a side project, I no longer have the setup so feel free to close it.
