[jira] [Commented] (AIRFLOW-166) Webserver times out using systemd
script
[ https://issues.apache.org/jira/browse/AIRFLOW-166?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15362684#comment-15362684 ]
Alexander Alten-Lorenz commented on AIRFLOW-166:
------------------------------------------------
Just changed the startup process to simple, which solved the issue. Any reasons why fork was used?

> Key: AIRFLOW-166
> URL: https://issues.apache.org/jira/browse/AIRFLOW-166
> Project: Apache Airflow
> Issue Type: Bug
> Affects Versions: Airflow 1.7.1.2
> Environment: CentOS 7
> Reporter: Yuri Bendana
>
> I just upgraded to 1.7.1.2 from 1.6 and I'm having a problem starting the webserver using the systemd script. This used to work fine. The issue is that it starts and then just hangs, no error is reported and it finally times out after about a minute. I tried starting it from the command line and it works fine without timing out. I also ran it in daemon mode with -D and again it seems to be fine. Any thoughts on how to debug this?
