Question

我正在部署到我正在使用Tomcat 7的VPS，我看到很多投诉部署了最多的Barebones grails app，例如：

  SEVERE: The web application [/BareBones-0.1] appears to have started a thread named [Timer-1]  but has failed to stop it. This is very likely to create a memory leak.

  SEVERE: The web application [/BareBones-0.1] appears to have started a thread named [H2 Log Writer PRODDB] but has failed to stop it. This is very likely to create a memory leak.

此外，即使我有1GB专用和2 GB突发，我经常只是重新部署WAR文件而耗尽内存。例如。当我运行Tomcat stop命令时，我得到：

 java.lang.OutOfMemoryError: PermGen space

在停止。

所以，我想知道是否有人可以给我一个指针，看看我是否可以在他们的经验中看到Jetty的问题。我的最终网络应用程序不会是一个非常大/重的交通网站。

它的known Tomcat issue非常频繁地发生（实际上我没有看到任何没有这种问题的应用程序）。这意味着您的应用程序出现了问题，或者（更常见）您的应用程序正在使用的库。有一个众所周知的错误列表＆＃39; - http://wiki.apache.org/tomcat/OutOfMemory

顺便说一下，有时在部署时重启Tomcat要容易得多，而不是使用热部署。

grails 2.0 - 在Jetty中运行，在Tomcat中运行
