我遇到了类似的问题，结果证明这只是您的工作test_3"持续时间太长，超过 5 秒(或您尝试的 2 分钟)).APScheduler 正在尝试重新执行您的作业，但前一个作业仍在运行.

I had a similar problem, and it turned out it was just your job 'test_3' lasting too long, more then 5 secs (or 2 minutes as you tried). APScheduler is trying to re-execute you job, but the previous one is still running.
