Laravel任务重复执行问题求助：单次调度任务多次触发

我在Laravel应用中遇到了任务重复执行的问题。仅调度了一次任务：

dispatch(new SendFirebaseNotificationJob($data));

但监控队列运行命令：

artisan queue:work  --sleep=3 --tries=0 --backoff=3 --max-time=3600

时，发现同一个任务的handle方法被多次触发（4次、6次甚至10次），日志如下：

2023-05-21 23:31:24 App\Jobs\SendFirebaseNotificationJob ..... 108.77ms DONE

已做排查：

• 检查过任务的幂等性
• 删除过数据库中的任务请求，避免重复调度

但问题仍存在，需要让任务仅执行一次，求解决建议或指导。
