> 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:
