Answer 1

-XX:MaxPermSize=512m 把这个加上

Answer 2

你启动tomacat的时候是不是加载的好几个项目  ？  最好将错误的项目去掉。 只加载最新的项目。

Answer 3

-Xms512m -Xmx1024m -XX:PermSize=128M -XX:MaxNewSize=512m -XX:MaxPermSize=256m -XX:SurvivorRatio=16
不知道楼主  那个配置 有点问题  我只会去 eclipse（myeclipse）里面配置 （当然使用的是你出问题的tomcat）preferences → tomcat → jvm setting → Append to JVM Parameters

Answer 4

打开服务器配置，在JDK里，Optional Java VM arguments一栏下就这句话：
-Xms256m -Xmx512m -XX:PermSize=128M -XX:MaxPermSize=256MOK，问题解决

Answer 5

其实你只要在tomcat.bat里加一段 -Xms256m -Xmx512m 代码就行了
