Error on Bench Restart after Control+C

This seems to be a recurrent error but there is no solution suggested.

If you interupt bench restart e.g. by pressing Control+C when in the middle of running, it becomes impossible to recover as bench restart doesn’t work thereafter.

     frappe-bench bench restart Traceback (most recent call last):

Is there a way to recover back from this?

We have tried:

  • Sudo supervisor restart all

  • sudo supervisor stop all, and then start all

  • sudo kill -9 sudo lsof -t -i:13001 and on port 12001, 11001 and 9001 without success
