Subject [jira] [Commented] (AIRFLOW-1003) DAG status flips erraticly
Date Thu, 22 Feb 2018 21:18:00 GMT

    [ https://issues.apache.org/jira/browse/AIRFLOW-1003?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16373463#comment-16373463
] 

Luke Bodeen commented on AIRFLOW-1003:
--------------------------------------

we turned down Gunicorn web server workers = 1

and saw this behavior diminish, long term if we need more workers we could also play with worker_refresh_interval
to lower that and see it for less time

> DAG status flips erraticly

>                 Key: AIRFLOW-1003
>                 URL: https://issues.apache.org/jira/browse/AIRFLOW-1003
>             Project: Apache Airflow
>          Issue Type: Bug
>          Components: ui
>    Affects Versions: Airflow 1.8, 1.8.0rc5
>            Reporter: Ruslan Dautkhanov
>            Priority: Major
>
> Created a flow based on sample tutorial https://airflow.incubator.apache.org/tutorial.html
> (just changed dag-id to 'turorial-RD').
> See a 10 seconds video on this behavior:
> http://screencast-o-matic.com/watch/cbebrn6kBw
> Notice last DAG 'turorial-RD' keeps changing state 
> (it loses link and all the buttons and icons to show status 
>  of the dag runs  / tasks etc), then links and icons show back up.
> In fact, during that short 10 seconds period it transitioned 
> that state 4 times (from "disabled" to a normal DAG).
> There were no changes happenning in the system - I was just clicking
> refresh in browser from time to time. All DAGs were disabled while
> this was happening.
