Previously, components that used AMQP for communication would log exceptions while the connection was being closed. Affected components included Compute (openstack-nova-compute), Compute Scheduler (openstack-nova-scheduler), and Compute Conductor (openstack-nova-conductor). These messages were benign. Errors reading from or writing to the recently closed socket are expected and do not require administrator attention.
With this fix, AMQP error logging is disabled while the connection is being closed.
