vincbeck opened a new pull request, #32971:
URL: https://github.com/apache/airflow/pull/32971
After long investigations, the test `test_send_tasks_to_celery_hang` is
responsible for many failures in different CIs (Airflow CI, AWS CI). This test
makes the tests hangs until there is a timeout. On Airflow CI, we have
experienced many failures in the CI with no logs/explanations, one possible
reasoning is this test.
Quoting @potiuk here in a Slack conversation to give more details:
> I think I see a slightly bigger number of jobs which are mystreriously
“failed” in CI without logs and my hunch tells me that we also experience this
race condition but the way how Github Actions works - if the test hangs without
accepting test timout, the logs from that Github Action job are lost when the
job is forcefully killed by GA framework on job timeout.
