When a task is deferred the `_try_number` is decremented so that when the trigger yields an event the task resumes execution where `_try_number` is incremented to use the same try_number before and after trigger. Perhaps when the task being cleared is in deferred state the try_number can be incremented. ```diff commit f08bc8d1326f2c7c271928d74804050c36b4e953 Author: Karthikeyan Singaravelan <[email protected]> Date: Tue Apr 9 11:10:06 2024 +0530 Increment try_number for cleared deferred tasks. diff --git a/airflow/models/taskinstance.py b/airflow/models/taskinstance.py index d52a71c5b2..62b4d3e821 100644 --- a/airflow/models/taskinstance.py +++ b/airflow/models/taskinstance.py @@ -274,6 +274,12 @@ def clear_task_instances( ti.state = TaskInstanceState.RESTARTING job_ids.append(ti.job_id) else: + # When the task is deferred the try_number is decremented so that the same try + # number is used when the task handles the event.
