JavierLopezT opened a new issue #9655: URL: https://github.com/apache/airflow/issues/9655
As far as I understand, the apparition of return code -9 when a task fails, is because the error is unknown. However, I have faced two situations when it was because of a lack of RAM (in my docker image): -MongoToS3Operator. I solved it modifying the operator and allowing to write on disk -Retrieving a dataframe with the dbapi hook, due to the size of the dataframe I have no clue if it is possible to identify when a problem has been because lacking of RAM, but if it is possible, maybe it would be nice to have a new code that specifies it ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
