Andy Loughran commented on AIRFLOW-1641:
----------------------------------------

How easy is that coding change; or is it a variable in airflow.cfg?

>    Affects Versions: 1.8.0

> Hello,
> I have one dag with ~20 tasks. 
> The dags runs daily and some tasks can sometime last for hours, depending on the processed
data behind.
> There are some interactions with AWS and a remote DB.
> I only use LocalExecutor.
> What this issue is about, is the fact that sometime (randomly, and without any clear
reason) one of the tasks (here also, it is random) gets stuck in "queued" state and never
starts running. 
> The manual workaround is to restart the task manually by clearing it.
> Does anyone have ideas about the issue behind, and how to avoid it for the future? 
> Thanks in advance for your help.
> PS: other people are facing the same behaviour: [link|https://stackoverflow.com/questions/45853013/airflow-tasks-get-stuck-at-queued-status-and-never-gets-running]
