+- `job_retry_buffer` determines the amount of time (in minutes) before stuck jobs will become eligible for automated retry processing to avoid potential edge cases, defaults to 1 minute
 - `job_retry_limit` how many stuck jobs can be retried per a single execution of `runQueue()`, set to `10` to disable job retries, defaults to `0` (globally disabled), recommended safe value is `10`
