vnf monitoring fails after multiple vnf create/delete operations

[Santosh]

1. Use following template to create a vnfd.

template_name: http-ping
description: http-ping-cirros-example

service_properties:
  Id: cirros-vnfd-http-moniotring
  vendor: canonical
  version: 1

vdus:
  vdu1:
    id: vdu1
    vm_image: cirros-0.3.4-x86_64-uec
    instance_type: m1.small
    user_data_format: RAW
    user_data: |
       #!/bin/sh
       cd /tmp
       rm -f httpsrv.sh
       cat > httpsrv.sh << EOL
       eth0_ip=$(ifconfig eth0|grep 'inet addr'|awk -F: '{print $2}'| awk '{print $1}')
       while true; do echo -e "HTTP/1.0 200 OK\r\n\r\nWelcome to $eth0_ip" | sudo nc -l -p 80 ; done&
       EOL
       sudo chmod +x httpsrv.sh
       sudo ./httpsrv.sh &
       sleep 180
       cat > kill << EOL
       cat <<'EOF' > kill
       pid = `ps -ef | grep httpsrv | grep exe | grep -v grep | awk '{print $1}'`
       echo "killing $pid"
       kill -9 $pid
       EOF
       sudo chmod +x kill

    network_interfaces:
      management:
        network: net_mgmt
        management: true

    placement_policy:
      availability_zone: nova

    monitoring_policy:
      http_ping:
        monitoring_params:
          monitoring_delay: 60
          retry: 5
          timeout: 10
          port: 80
        actions:
          failure: respawn

    config:
      param0: key0
      param1: key1

2. Create 8 vnfs with above template. Notice, vnf should respawn approximately every 3 minutes.
   Verify all vnfs respawn after every 3 mins.
3. Run the functionality testcases using "tox -e functional" . In functionality test, there are multiple create/delete vnfs .
4. After the tests are run some of vnfs will go to ERROR state (because of lack or resource - assuming only 10 vm instances is maximum possible). At this point you will notice monitoring doesn't happen and vnfs are not restarted at all

I tested this scenario on current master code with user_data/config mentioned in bug description.
But could not reproduce it.

@Santosh,
Could you please mention the tacker version, Or please test on master.
