"circus.exc.ConflictError: arbiter is already running arbiter_start_watchers command"

We can set check_delay to a higher value to avoid checking before the processes all started successfully.

But there may be a better way to notify the checker all processes got up and run, you can check them periodically now. Use a Event ? CountDownLatch ? to coordinate the flow.
