Title:
  neutron unittest require minimum 4gb memory

Status in OpenStack Neutron (virtual network service):
  Confirmed
Status in neutron havana series:
  Fix Released

Bug description:
  tox -e py26

  The unittest hang forever. Each test seem to take around 25mins to
  complete. Each test report following error, though it is PASS. It
  sounds like a regression caused by fix for
  https://bugs.launchpad.net/neutron/+bug/1191768.

  https://github.com/openstack/neutron/commit/06f679df5d025e657b2204151688ffa60c97a3d3

  As per this fix, the default behavior for
  neutron.agent.rpc.report_state() is modified to use cast(), to report
  back the state in json format. The original behavior was to use call()
  method.

  Using call() method by default might fix this problem.
