我正在使用 tomcat 7.x ，当我在一段时间后启动服务器时出现以下错误。
Sep 17, 2011 4:46:53 PM org.apache.catalina.startup.Catalina stopServer

在此之后我检查了所有泄漏的连接和其他资源，我的应用程序完全正常。
但是当这个错误出现时，我必须重新启动我的电脑。即使在重新启动服务器后，这也是不可恢复的。
我正在粘贴我的 netstat -a，在这个问题出现之前和问题出现之后。

任何人都可以帮助我理解这个 netstat 吗？现在这个问题经常出现。
最佳答案
听起来您的交换空间不足。如果重新启动应用程序没有帮助，则表明另一个应用程序正在使用内存。当您停止应用程序时，它会释放该应用程序使用的所有资源。即重新启动了错误的应用程序。
发生这种情况时，您能确定退出 tomcat 后还有多少空闲内存可用吗？如果它很低，那么最大的内存消耗者是什么？
能不能增加机器的交换空间，或者更好的增加机器的物理内存？
你能减少其他应用程序的内存消耗吗(或者 tomcat，如果它被证明是问题，但听起来不像)
