[GitHub] [airflow] mik-laj opened a new pull request #11734: Improve web server stopping
mik-laj opened a new pull request #11734:
URL: https://github.com/apache/airflow/pull/11734
If we send signal SIGTERM - 15 several times to airflow webserver, then gunicorn can become [defunct process](https://askubuntu.com/questions/201303/what-is-a-defunct-process-and-why-doesnt-it-get-killed) and Airflow will not be able to handle this situation and will wait in an endless loop. Re-sending the signal to Airflow will cause it to re-send the signal SIGTERM - 15 to gunicorn (but it will not receive it anyway) and then re-enter the endless loop. As a result, Airflow can only be stopped by signal SIGKILL - -9.
It is possible that it will fix some of the tests we have in quarantine.
