寻求帮助。Jetty 8.1.14.v20131031在EC2 Ubuntu 12.04上运行。它在启动后3小时内自动关闭。只是为了确认这不是我的代码问题，我从服务器中删除了战争文件，并从默认[spdy.war and test.war]开始，但是结果相同。3小时后，它被关闭了。Jetty不会在日志中记录任何错误。只是提到这个问题始于一个月前，在此之前运行良好。
这是日志 -

注意：Jetty 8是EOL（生命的尽头），请考虑升级。
这个问题并不是真正适合Stackoverflow，因为它不是编程问题。
这个问题将在ServerFault的amazon-web-services标签上更适合。
2016-11-28 21:11:27.567:INFO:oejs.Server:Graceful shutdown表示某人（或码头之外的某个过程）专门告诉它关闭。
这不是偶然的，也不是码头决定自己关闭，看着码头外面寻找答案。（服务配置，CRON，AWS配置，其他用户等）
我开始忽略吊架信号的码头，而目前这项工作似乎在起作用。我使用此命令[nohup java -jar start.jar＆amp;]开始了码头。但是关闭信号的根本原因仍然远离我的视线。
