当您的webapp运行时，这大概不会导致问题，只是当您使用Tomcat管理器停止webapp时，您看到了这些错误

Tomcat无法释放Web应用程序使用的所有内存，因此在某个时候，如果反复重新启动Web应用程序，Tomcat将耗尽内存。看起来您正在创建许多未清理的线程局部变量

你的选择是：

找出为什么这些本地人没有被清理。关于跟踪Tomcat中的这种内存泄漏，有很多信息
重新启动Tomcat本身，而不是使用Tomcat manager重新启动您的Web应用程序。如果您在Tomcat实例中有任何其他实时Web应用程序，这不是一个好的选择，但如果您的Web应用程序是唯一的，则完全可以接受
上面的一个变体是：使用管理器重新启动您的webapp，但注意它正在使用多少内存（泄漏可能不是特别严重）。然后在必要时重新启动Tomcat。您可能会发现，在需要完全重新启动Tomcat之前，您可以安全地重新启动webapp很多次

我不确定您使用的是哪个版本的struts2，请确保用struts2标签标记您的struts2问题，否则您将无法获得适当的注意

这是struts2早期版本中的已知错误之一，该错误在

2.3.3

中得到修复。停止/取消部署/重新部署S2应用程序时，localContext ThreadLocal未正确清理。在大多数情况下，这将导致web应用程序类加载器不会被垃圾收集，从而导致内存泄漏

请交叉检查您使用的Struts2版本，如有必要，请将其升级至最新版本

有关更多详细信息，请参阅Tomcat内置了对某些永久性生成内存泄漏情况的检测。这是我不久前写的一篇博文，解释了PermGen泄漏的原因：。您应该检查应用程序，找出Tomcat发现的问题的原因。我觉得那些日志很容易解释。

你的问题是什么？你刚才说了一些你观察到的事情。你提到的第二个选项是错误的，停止tomcat本身而不是使用app manager没有什么区别。Tomcat无论如何都会记录这些消息，因为它会在关闭自己之前关闭应用程序。只是想把事情弄清楚。
