the scheduler cannot

complete the task assigned to it because it may be overloaded with too many tasks or there may be conflicts with other tasks. It may also encounter errors or bugs that prevent it from functioning properly. In such cases, the scheduler may need to be adjusted or reconfigured to optimize its performance and ensure that all tasks are completed efficiently.

The Scheduler cannot be restarted after shutdown() has been called.

这是一个编程类的问题，可能是由于在调用 shutdown() 方法后尝试重新启动调度程序导致的错误。建议检查代码中的调度程序实现，确保正确地使用了 shutdown() 和 start() 方法。如果需要更具体的帮助，请提供更多的上下文和代码细节。

Exception in thread "Quartz Scheduler [RuoyiScheduler]" org.springframework.scheduling.SchedulingException: Could not start Quartz Scheduler after delay; nested exception is org.quartz.SchedulerException: The Scheduler cannot be restarted after shutdown() has been called. at org.springframework.scheduling.quartz.SchedulerFactoryBean$1.run(SchedulerFactoryBean.java:753)

这个错误是由于在调用了Quartz Scheduler的shutdown()方法之后，再次尝试启动Scheduler时发生的。因为Quartz Scheduler一旦关闭，就不能再次启动。

解决办法是在启动Scheduler之前，确保它没有被关闭。你需要检查你的代码，查看是否在调用shutdown()方法之后尝试启动Scheduler。如果是，则需要修改代码以避免这种情况的发生。
