Kengo Seki commented on AIRFLOW-1121:
-------------------------------------
Yeah, that's my fault. I mistakenly assumed that pid file is unnecessary if
webserver runs in the foreground.
Thanks for the notification Sid, I'll submit a PR today if possible.
> airflow webserver --pid no longer write out pid file!

> Key: AIRFLOW-1121
> URL: https://issues.apache.org/jira/browse/AIRFLOW-1121
> Project: Apache Airflow
> Issue Type: Bug
> Components: webserver
> Affects Versions: 1.8.1rc0
> Reporter: Siddharth Anand
> Priority: Blocker
> Fix For: 1.8.1
>
>
> I've run into a regression with the webserver. It looks like the --pid
> argument is no longer honored in 1.8.1. The pid file is not being written
> out! As a result, watchdog processes like monitd, which watch the processes
> mentioned in the pid file, keep trying to spawn webservers because the pid
> files are not being written.

> If I include -D, things work:
> airflow webserver -D --pid ~/this.pid

> 8732
> 8735
> However, this doesn't help me as I don't want to run with -D.
