 Hi All

We have a Openstack setup with the Ussuri Version and I am regularly facing auto shutdown of a few VMs (ubuntu16.04) randomly .
If I restart then the instance is back .

From logs I was able to see the messages below .

 WARNING nova.compute.manager [req-2a21d455-ac04-44aa-b248-4776e5109013 813f3fb52c434e38991bb90aa4771541 10b5279cb6f64ca19871f132a2cee1a3 - default default] [instance: 28cd861c-ef15-444a-a902-9cac643c72b5] Received unexpected event network-vif-unplugged-e97839a1-bbc4-4d26-af30-768ca3630ce9 for instance with vm_state active and task_state None.

I searched a few blogs and forums but couldn't find a solution to it .

Few mentioned to add sync_power_state_interval=-1 in /etc/nova/nova.conf .But understood that this will help only when nova stops vm.
But in this case vm itself is shutting down (Instance shutdown by itself. Calling the stop API) 
Also no memory issue in VM nor the hypervisor.
Also did apt-get upgrade .

It would be great if anyone can shed light to this issue.
