Title:
  heartbeating is broken with kombu

Status in OpenStack Compute (Nova):
  Fix Released
Status in Oslo - a Library of Common OpenStack Code:
  Fix Released

Bug description:
  This review:

  https://review.openstack.org/#/c/34949/3

  Added a heartbeat config to kombu... however, kombu requires that you
  call heartbeat_check() periodically to verify that the heartbeats have
  been received.  No such call was added.

  This results in kombu closing the connection every 60 seconds or so
  (the default heartbeat config) and causing a lot of tracebacks in logs
  when trying to consume messages.  kombu ends up raising 'Socket
  closed' and reconnecting:
