Did it actually kill the nova-compute service or just complain in the logs?  The 
release notes for nova in Ocata say:

     The nova-compute worker now communicates with the new placement API
     service. Nova determines the placement API service by querying the
     OpenStack service catalog for the service with a service type of
     'placement'. If there is no placement entry in the service catalog,
     nova-compute will log a warning and no longer try to reconnect to the
     placement API until the nova-worker process is restarted.
