Backfill job deadlocked error

[shivboom q]

Hi Team,

We have dag composed of subdags, when one or more dags are running in
parallel we are facing below error,

*Backfill job is deadlocked*

Can someone explain what’s the cause of the error and how to solve this?

Version: 1.10.0( celery executor)

Note: we are getting this error only for subdags.


Regards,
Shiv
