Polling Sensor - polling twice always

I mean to say - my polling sensor is polling twice at the same instance of time … I doubt two instances of the sensor are running at the same time …

Can anyone help how can i stop the current polling sensor and restart it.

If sensor is ran in Debug mode - will it create a new instance of the existing one?

Yes, you need to run only single replica of the sensor.

You can check the running linux processes to check if there are any unexpected copies.
