tomcat发布工程，内存溢出，请高手们进来指点
前提条件
tomcat7
jdk7
发布到tomcat7的webapp 大小 250M
已经试过的办法，配置tomcat的内存参数没用，配置JDK的内存参数没用，配置Myeclipse的内存参数没用。
核心错误信息如下

请各位高手指点啊。。不然就没法工作了。。同事们跟我一样的环境也没出这个问题。请指点。
tomcat 内存溢出??
[解决办法]
看看这篇http://blog.csdn.net/lifetragedy/article/details/7708724
[解决办法]
正常的tomcat部署不会出现内存益处,有可能你在tomcat下面部署的工程过多,那些不用的工程都去掉;也有可能是你webroot下面粘贴了一些别的架库,看似导入的那些架库文件不大,有时候只有两三兆,但是经过tomcat部署之后,实际需要jvm的内存远远大于表面想的.如果是这样,就选择性的复制一些需要的文件,不用的东西不要copy进去
[解决办法]
设置MaxPermSize大小
TOMCAT_HOME/bin/catalina.bat 文件头加
set JAVA_OPTS='-Xms512m -Xmx1024m -XX:MaxPermSize=512m'

老问题
[解决办法]
以前我也有遇到过部署项目内存益处的情况,是因为在webroot下面直接粘贴了extjs库(3m左右),在部署的时候,查看到虚拟机的内存占用达到了500m,一般2g(4g)物理内存的jvm的最大内存只有512m(1g),在jvm可用内存少于最大内存的5%时,部署就发生内存益处.你把jvm内存监测的那个工具打开,查看一下部署项目时,jvm具体使用内存的大小.尽可能的关掉那些没必要的程序,在eclipse中保留当前项目,其他的全部delete
