Hi rishi, we are unable to stop the service. we checked earlier and found there is no pid running in background. once we restart the server that service will come up and after few seconds will go down.

Kindly assist asap since we unable to fix it.

Thanks.

Looks like neutron-openvswitch-agent died badly. Check the logs, including system logs for hints on why that happens. Edit your question to add more details as you work on this issue.
