### Search before asking - [X] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar issues. ### What happened 3.1.8版本 举例：调度定时执行工作流（每半小时一次），但执行时偶尔一下会拉起两个任务。 在任务实例中可看到同一时间调起了两个工作流。如果是明细表，则会造成数据插入两倍。如下图所示，每半小时一次的任务，在13:30分的时候，执行了两次。  ### What you expected to happen 查看dolphion master日志，发现确实执行了两次。 查看源码，日志打印（dolphinscheduler-scheduler-quartz ， ProcessScheduleTask 64行） scheduled fire time :{}, fire time :{}, process id :{} 同一个process id 在不同的master节点都被调用了 。 ### How to reproduce 每天有1%左右的任务都会重复 ### Anything else _No response_ ### Version 3.1.x ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
