URL: https://github.com/apache/airflow/issues/7935#issuecomment-606489074
I'm running Airflow 1.10.4 as Celery in k8s. The scheduler pod is getting stuck while starting up at the step 'Resetting orphaned tasks'.
```

```
This causes the UI to say
> The scheduler does not appear to be running. Last heartbeat was received 5 minutes ago
The same thing happens even after restarting the scheduler pod. (regardless of the CPU usage)
Any leads to solve this?
