问题描述
我工作的大学使用Tomcat / Railo服务器渲染ColdFusion页面。在大约6个月的时间里（在我被雇用之前），服务器在不同的时间随机崩溃，通常运行正常的服务railo_ctl restart 已修复了hte问题，但是最近还没有解决
The university I work at uses a Tomcat/Railo server to render ColdFusion pages. For about 6 months (before I was hired) the servers have been randomly crashing at different times, usually runnign service railo_ctl restart has fixed hte issue, however lately this hasn't been working as well.
在过去的两周中，我已经缩小了问题的范围，而且我很确定问题的根源是Tomcat。我从未使用过Tomcat，所以不确定从哪里开始。我查看了Catalina.out文件，并查看服务器崩溃的时间，发现此错误消息：
Over the past two weeks I've narrowed the issue down, and I'm fairly sure Tomcat where the issue is coming from. I've never used Tomcat, so I'm not sure where to start. I have reviewed the Catalina.out files, and looked at the time when the servers crashed and found this error message:

SEVERE: The web application [] is still processing a request that has yet to finish. This is very likely to create a memory leak. You can control the time allowed for requests to finish by using the unloadDelay attribute of the standard Context implementation.

I also noticed that this error came up, but it doesn't seem to pop up the same time the servers crashed

推荐答案
我相信这是您问题的根源：
I believe this is the root of your problem:
严重：Web应用程序[]仍在处理尚未完成
的请求
SEVERE: The web application [] is still processing a request that has yet to finish
您的应用程序中的某些东西导致线程挂起，并可能死亡。不幸的是，这类错误非常难以诊断。如果您是我，我会做的是使用FusionReactor之类的工具监视应用程序，并特别注意应用程序中长时间运行的请求。这样可以提供有关您的应用程序是什么引起这些问题的线索。
Something in your app is causing a thread to hang, and probably die. Unfortunately these kinds of errors are extremely difficult to diagnose. What I would do, if I were you, is to monitor the app with something like FusionReactor, and watch in particular for long running requests in your app. This could provide clues as to what piece of your app is causing these problems.
我会将FusionReactor安装在单独的Tomcat实例中，以便可以监视您的应用程序直至直到死亡。再次，这可以提供更多线索来确定确切的线程正在挂起和/或垂死。
I would install FusionReactor in a separate instance of Tomcat so that it could monitor your app up to and after the point of it's death. Again, this could provide more clues as to what exact threads are hanging and/or dying.
FusionReactor是一种商业产品，但附带30天试用版，其中功能齐全。如果您要管理该应用程序，则许可证可能会很值得，但是如果您不能随意使用，则还有其他JVM监视产品，例如VisualVM等。它们虽然不如FusionReactor那样具有针对性，但它们仍然可以提供帮助。
FusionReactor is a commercial product but comes with a 30 day trial in which it is fully functional. If you're going to be managing this application, a license is probably going to be worthwhile, but if you can't swing that, then there are other JVM monitoring products like VisualVM and the like. They're not as targeted as FusionReactor, but they still might be able to help.
