Hi,

This is a well known issue when eventlet monkey patching is not done 
correctly.
The application must do the monkey patching before anything else even 
loading another module that eventlet.

You can find more information here: 
https://bugs.launchpad.net/oslo.messaging/+bug/1288878

Or some examples of how nova and ceilometer ensure that:

  https://github.com/openstack/nova/blob/master/nova/cmd/__init__.py
  
https://github.com/openstack/ceilometer/blob/master/ceilometer/cmd/__init__.py


More recent version of oslo.messaging already outputs a better error 
message in this case.

Cheers,
