[GitHub] [airflow] yergi commented on issue #14205: Scheduler "deadlocks" itself when max_active_runs_per_dag is reached by up_for_retry tasks

   I think the issue I'm experiencing is related to this. 
   
   Apache Airflow version: 2.0.1
   Executor: LocalExecutor
   
   What happened: I have `max_active` set to 4, and when running a backfill for this dag, if 4 sensor tasks get set for `up_for_reschedule` at the same time, the backfill exits telling me that all the tasks downstream for these sensors are deadlocked.
