msempere created AIRFLOW-5071:
---------------------------------
Summary: Thousand os Executor reports task instance X finished
(success) although the task says its queued. Was the task killed externally?
Key: AIRFLOW-5071
URL: https://issues.apache.org/jira/browse/AIRFLOW-5071
Project: Apache Airflow
Issue Type: Bug
Components: DAG, scheduler
Affects Versions: 1.10.3
Reporter: msempere
I'm opening this issue because since I update to 1.10.3 I'm seeing thousands of
daily messages like the following in the logs:
```
{\{__init__.py:1580}} ERROR - Executor reports task instance <TaskInstance: X
2019-07-29 00:00:00+00:00 [queued]> finished (success) although the task says
its queued. Was the task killed externally?
{\{jobs.py:1484}} ERROR - Executor reports task instance <TaskInstance: X
2019-07-29 00:00:00+00:00 [queued]> finished (success) although the task says
its queued. Was the task killed externally?
```
And looks like this is triggering also thousand of daily emails because the
flag to send email in case of failure is set to True.
I have Airflow setup to use Celery and Redis as a backend queue service.
