DAGS disappear from UI [2.5.1] #30363
Description
Apache Airflow version
Other Airflow 2 version (please specify below)
2.5.1
What happened
Hello,
Since upgrading to 2.5.1, we have noticed the sporadic disappearance of DAGs from the web UI. Sadly, we have not been able to reproduce it reliably. As such, this bug report is unfortunately lacking in details and is meant to hopefully get some ideas on how to approach debugging this.
One thing we have determined brings the DAGs back is to run airflow dags reserialize. It's worth noting that the DAG files are still on disk when missing in the UI. They also fail to show up in airflow dags list. Additionally, we believe, but are not certain, that the DAGs are still getting scheduled and executing work despite being absent in the web UI.
What you think should happen instead
DAGs should not disappear.
