Title:
  The number of neutron-ns-metadata-proxy processes grow uncontrollably

Status in OpenStack Neutron (virtual network service):
  Expired

Bug description:
  During testing and development I had to add and remove instances, routers, ports often. Also I restarted all neutron services often ( I use supervisor ).
  After about one week, I noticed that I ran out of free RAM. It turned out there were tens of neutron-ns-metadata-proxy processes hanging. After I killed them and restarted neutron, I got 4 GB RAM freed.
