Question

我有一个在Tomcat 7.0.57中部署的Grails 2.3.6版本应用程序

我已将WAR文件放在Tomcat的webapps文件夹中。当我进行服务器启动时，我在控制台窗口中获得异常。看起来部署正在进行，并且在一段时间后抛出异常。

请参阅下面的stacktrace：当我转到Windows任务管理器时，jave.exe占用了近70％-80％的CPU。

Answer 1

Grails使用的内存比您预期的多，并且由于在运行时创建的动态代码而使用更多的permgen。你不应该那么多地增加permgen - 首先尝试将它设置为256MB。

为permgen和其他类似设置放置JVM args的最佳位置是在Tomcat的bin目录中的setenv.sh（或Windows上的.bat）。它不是默认创建的，并且不需要可执行，但它使用与shell脚本相同的格式。任何导出的变量都将用于catalina.sh

这应该是足够的总堆和permgen：

export CATALINA_OPTS="-Xms256m -Xmx768m -XX:MaxPermSize=256m"

Grails：Tomcat War文件部署给出内存异常
