Hey there, we're observing the same issue on Airflow 2.1.4 in a big DAG having hundreds of tasks. By looking in the scheduler logs from the moment when the downstream task was marked as `upstream_failed` it seems that it happened when a pod with the upstream task could not be started. ``` Failed to start pod ... ``` Also, looking at the successful task, it indeed has two tries, from which the first one really finished at the incriminated timestamp.  -- This is an automated message from the Apache Git Service.
