重新整理一下关于Tomcat问题:java.lang.OutOfMemoryError: PermGen space 0

这几天一直在上网找相关问题解决方案..
但是到的答案, 大部分都是增加JVM 内存.
方法:
在 catalina.bat 中增加:
set JAVA_OPTS=-server -Xms1024m -Xmx1024m -XX:PermSize=256m
或
JAVA_OPTS = "-server -Xms1024m -Xmx1024m -XX:MaxNewSize=256m"
或
JAVA_OPTS="-server -XX:PermSize=512M -XX:MaxPermSize=768m
之类的解决方案.
但是我已经讲其参数设置为
set JAVA_OPTS =-Xms10240m -Xmx10240m -XX:MaxPermSize=2560m
PS:主机内存16G CUP 8核 是志强E5606CPU
但是内存溢出现象仍然存在!
下面是错误信息...
大家还有什么解决办法???
比如快速排查java应用的内存使用情况>>

   修改JVM的参数这个思路是正确的,就是要把-XX:PermSize=64M -XX:MaxPermSize=128m设大点，但问题是这个数字不能无限乱设定，设置很大却不起作用的原因可能是jvm认为这个参数值不合理，然后就用了默认值，默认值-XX:MaxPermSize=64m，所以仍然可能会出错。
   所以最保险的办法是用设置重启tomcat后，用jmap来观察是否起作用了，当前jvm到底是用什么数值。

你都设置这么大了内存还爆掉，当然要看是哪里耗了这么大内存了。

1.建议把启动比较全的日志贴出来，看看内存设置有没有起作用
2.如果已经起作用的话，这个溢出一般是在什么时候抛出？启动抛出还是运行一段时间抛出，简要介绍下项目中的结构和背景，然后我们在分析

我记得Xms和-Xmx这个是配置堆的大小
他和perm空间是反比的，内存像块蛋糕，堆空间多了方法区空间就少了，反之亦然。。

建议使用jconsole看看，是不是线程数一直彪上去，没有下来过？

你这异常报的是永久保存区域PermGen溢出，应该在catalina.bat 中将
-XX:PermSize=64M -XX:MaxPermSize=128m设大点

用JDK自带的那个jvisualvm.exe工具查看一下当前是什么地方占用的内存
