[GitHub] [airflow] michaelosthege edited a comment on issue #7935: scheduler gets stuck without a trace

   I had ~4800 tasks from the same DAG stuck after a manual reset, with the scheduler just killing PIDs.
   Turning other DAGs off and increasing `DAGBAG_IMPORT_TIMEOUT` did not help. Also restarting webserver/scheduler/redis/mysql had no effect.
   
   After setting the "running" dagruns with the stuck tasks to "failed" and then back to "running" in smaller batches the scheduler managed to queue them.
   
   (Airflow 1.10.10 with Celery)
