Hi Fokko, This would be difficult to test. I am not sure of the condition when it occurred. Our DAG runs nightly and this has happened once in the past three months.
If this is something that has been identified and fixed in 1.10, I can make an attempt to upgrade it. But I did not see anything related to this in the changelog.

Maybe write a dummy dag, and run it using Docker.
