Re: [I] Standalone DAG Processor Causes DAGs to Appear and Disappear Frequently in Production [airflow]

lightning-L commented on issue #44652:
URL: https://github.com/apache/airflow/issues/44652#issuecomment-3276849499

   We also met similar issue in our production environment. We have 10,000+ dags, and the total dag processing time is 1~2 hours.
   Our workaround is to set dag_stale_not_seen_duration to a very large number, like 7200.
   
   The issue (DAG disappearing and reappearing) is really confusing for our users, even though most of the DAGs are not changed for a long time.
