Hey this maybe help for you:
When an autorestarting process is in the BACKOFF state, it will be automatically restarted by supervisord. It will switch between STARTING and BACKOFF states until it becomes evident that it cannot be started because the number of startretries has exceeded the maximum, at which point it will transition to the FATAL state. Each start retry will take progressively more time.
so you don't need to stop the BACKOFF process manually. if you do not want to wait too long time, it is better to set a little number to startretries.
