> A short retry interval leads to a divide by zero error. To replicate, create a DAG with a short retry interval (1 second), and eventually the following error will appear:
> ```
> Traceback (most recent call last):
> ...
>  File "/app/airflow/models/taskinstance.py", line 630, in next_retry_datetime
>  modded_hash = min_backoff + hash % min_backoff
> ZeroDivisionError: integer division or modulo by zero
> ```
