Quartz 调度程序突然停止并且无法处理线程
Quartz schedular stops suddenly and it is not able to handle threads
我们当前的应用程序是 运行 在 glassfish 和 windows 服务器上。我们现在将应用程序移至 linux 服务器上的码头和 运行。
应用程序中有一个 quartz 作业，它每分钟运行一次，并从远程服务器获取 ftp 文件。
最近发现作业突然停了，quartz也没有异常。
我添加了一个quartz.properties文件并配置如下，
org.quartz.scheduler.skipUpdateCheck = true
org.quartz.scheduler.instanceName = MyQuartzScheduler
org.quartz.scheduler.jobFactory.class = org.quartz.simpl.SimpleJobFactory
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount=10
org.quartz.scheduler.jmx.export = true
org.quartz.scheduler.threadName="QuartzThreadFa"
我也实现了 quartz 停止工作后的线程转储（应用程序 运行 没有任何错误）
在线程转储中，我看到石英正在使用所有线程，直到线程计数结束。并且所有线程都被对象锁定，
线程转储；

问题是该应用程序 运行 几年了，在 Glassfish /Windows 上没有任何石英问题，
现在它只是 运行 直到线程计数在 Jetty/Linux 结束并且它无法 stop/kill 线程。
任何帮助将不胜感激，谢谢
看起来不是您的 Quartz 调度程序的问题。
从您的线程转储来看，org.apache.commons.net.ftp.FTPClient（来自 com.fatr.myApp.trawler.jobs.FtpJob 的 运行）似乎有问题并耗尽了您的所有线程。
这个问题看起来像是 FTPClient（在 lx 服务器上）和 FTPServer 之间的问题。来自 Linux 的 FTPClient 在某个时间点后挂起。由于 FTPClient（在本例中为 Linux）和服务器之间通信的不寻常性质，应在 Client（Linux Server）上打开某些端口号，以便 FTPServer 发送回数据。但是由于防火墙的限制，大多数这些非特权端口在 Linux 上都关闭了。显然，每次来自 FTPClient 的请求似乎 FTPServer 使用不同的端口，其中一些在 Linux.
上未打开
解决方案看起来像FTPClient进入"PASSIVE"模式。在被动模式下，FTPClient(on Linux) 为服务器打开一个专用端口来发送回数据。
所以根据这些信息，我将FTPClient设置为被动并再次部署。
FtpClient.enterLocalPassiveMode()
它现在可以正常工作了。
我们当前的应用程序是 运行 在 glassfish 和 windows 服务器上。我们现在将应用程序移至 linux 服务器上的码头和 运行。 应用程序中有一个 quartz 作业，它每分钟运行一次，并从远程服务器获取 ftp 文件。 最近发现作业突然停了，quartz也没有异常。
我添加了一个quartz.properties文件并配置如下，
org.quartz.scheduler.skipUpdateCheck = true
org.quartz.scheduler.instanceName = MyQuartzScheduler
org.quartz.scheduler.jobFactory.class = org.quartz.simpl.SimpleJobFactory
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount=10
org.quartz.scheduler.jmx.export = true
org.quartz.scheduler.threadName="QuartzThreadFa"
我也实现了 quartz 停止工作后的线程转储（应用程序 运行 没有任何错误）
在线程转储中，我看到石英正在使用所有线程，直到线程计数结束。并且所有线程都被对象锁定，
线程转储；

问题是该应用程序 运行 几年了，在 Glassfish /Windows 上没有任何石英问题， 现在它只是 运行 直到线程计数在 Jetty/Linux 结束并且它无法 stop/kill 线程。 任何帮助将不胜感激，谢谢
看起来不是您的 Quartz 调度程序的问题。
从您的线程转储来看，org.apache.commons.net.ftp.FTPClient（来自 com.fatr.myApp.trawler.jobs.FtpJob 的 运行）似乎有问题并耗尽了您的所有线程。
这个问题看起来像是 FTPClient（在 lx 服务器上）和 FTPServer 之间的问题。来自 Linux 的 FTPClient 在某个时间点后挂起。由于 FTPClient（在本例中为 Linux）和服务器之间通信的不寻常性质，应在 Client（Linux Server）上打开某些端口号，以便 FTPServer 发送回数据。但是由于防火墙的限制，大多数这些非特权端口在 Linux 上都关闭了。显然，每次来自 FTPClient 的请求似乎 FTPServer 使用不同的端口，其中一些在 Linux.
上未打开
解决方案看起来像FTPClient进入"PASSIVE"模式。在被动模式下，FTPClient(on Linux) 为服务器打开一个专用端口来发送回数据。
所以根据这些信息，我将FTPClient设置为被动并再次部署。
FtpClient.enterLocalPassiveMode()
它现在可以正常工作了。
