Quartz 2.2.3在一段时间后停止计划下一个作业

Question

Quartz 2.2.3在一段时间后从线程转储中停止计划下一个作业，我们可以知道所有处于TIMED_WAITING状态（正在等待可运行）的Worker，但是QuartzSchedulerThread阻止了可用线程：

“我的工作”用于下载文件，大小可能在1MB到1GB之间。有时我会从日志中发现以下错误：

[2018-11-09 00:11:25.591] [ERROR] [downloaderScheduler_Worker-10] SimpleThreadPool Worker thread was interrupt()'ed.
java.lang.InterruptedException: null
        at java.lang.Object.wait(Native Method)

这是一个线程转储：
