我有一个任务Airflow 2.1.2以成功状态完成，但在该日志显示一个 sigterm 之后：
[2021-12-07 06:11:45,031] {python.py:151} INFO - Done. Returned value was: None

如您所见，第一行返回Done，并且此日志的前几行显示所有脚本都运行良好并且数据已插入Datawarehouse.
在第 8 行中，它显示SIGTERM由于一些外部触发器将其标记为成功，但我确信没有人使用API，或者CLI将其标记为成功也没有UI. 知道如何避免它，为什么会发生这种情况？
我不知道是否可能增加AIRFLOW_CORE_KILLED_TASK_CLEANUP_TIME可以解决它，但我想了解它。
