Essex3 : AttributeError: 'Connection' object has no attribute 'connection_errors'

Hello,

I am trying to setup an OpenStack Cloud environment from the essex-3 packages available on launchpad.

I have an issue when I try to start nova-scheduler and nova-network (see below).
kumbo == 1.0.4
amqplib == 0.6.1

Thank you very much for your help.

Regards,
Jérôme
