> Project: Apache Airflow
> Issue Type: Bug
> Components: backfill, scheduler
> Affects Versions: 1.10.1
> Reporter: Ignas
> Priority: Blocker
>
> When a task in a successful backfill run is cleared DagRun with running state
> is created but it is not picked by the scheduler.
> If there are many of such DagRuns and the backfill command is executed, all
> the DagRuns will be ran at the same time, not following the max_active_runs
> parameter.
