### Apache Airflow version Other Airflow 2 version (please specify below) ### If "Other Airflow 2 version" selected, which one? 2.5.3 ### What happened? A certain task ran and exceeded the set SLA miss timeout period, then triggered an SLA miss event. The pre-written SLA miss callback function was called, and alarm messages were sent to the DingTalk group. Now there are some tasks that trigger SLA miss multiple times. The corresponding callback functions are called, and alarm messages are sent to DingTalk multiple times as well. The alarm contents are exactly the same. I don't know how to handle this. ### What you think should happen instead? The callback function for the SLA miss of the task is only invoked once and only one alarm message is sent. ### How to reproduce It occurs occasionally at present and we still don't know how to reproduce it. ### Operating System CentOS Linux 7 (Core) ### Versions of Apache Airflow Providers _No response_ ### Deployment Official Apache Airflow Helm Chart ### Deployment details _No response_ ### Anything else? _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
