Title:
  BSN consistency hash not multi-server safe

Status in OpenStack Neutron (virtual network service):
  Fix Committed
Status in neutron juno series:
  In Progress

Bug description:
  Multiple neutron servers may read from the consistency hash table in
  the big switch plugin simultaneously, which will cause the one with a
  later request to receive an inconsistency error.

  This is an issue with RPC induced backend requests (port update) or
  active-active deployments.
