ephraimbuddy opened a new pull request #17786: URL: https://github.com/apache/airflow/pull/17786
Currently, tasks can be run even if the `dagrun` is queued. Task instances of queued `dagruns` should only be run when the `dagrun` is in a running state. This PR makes sure `tis` of queued `dagruns` are not run thereby properly checking task concurrency. Also, we check max_active_runs when parsing dag which is no longer needed since `dagruns` are created in `queued` state and the scheduler controls when to change the queued `dagruns` to running considering the max_active_runs. This PR removes the checking of max_active_runs in the dag too. --- **^ Add meaningful description above** Read the **[Pull Request Guidelines](https://github.com/apache/airflow/blob/main/CONTRIBUTING.rst#pull-request-guidelines)** for more information.
