Title:
  L3 and DHCP agents may hang while processing a router or a network

Status in neutron:
  Invalid

Bug description:
  In some cases when L3 agent is restarted, it can't detect that ns-
  metadata-proxy process is already running in the qrouter-namespace so
  L3 agent spawns it again and again with each restart.

  After some number of ns-metadata-proxy processes running in a namespace, L3 agent hangs on spawning additional process.
  The symptoms are that router processing loop is getting stuck on one of the router, so remaining routers are not processed.

  The workaround is to kill ns-metadata-proxy processes from that
  router's namespace and restart L3 agent.

  Similar problem appears with DHCP agent in case metadata is turned on
  and network is isolated.
