tomcat内存问题

启动故障故障现象:

tail -f logs/catalina.out

z/**] onto handler 'org.springframework.web.servlet.resource.ResourceHttpRequestHandler#1'
[2012-12-17 11:35:54:300] [main] INFO  (org.springframework.web.servlet.handler.SimpleUrlHandlerMapping:411)  - Mapped URL path [/common/**] onto handler 'org.springframework.web.servlet.resource.ResourceHttpRequestHandler#2'

# A fatal error has been detected by the Java Runtime Environment:

解决方法:
查看apache-tomcat-gdxxw/hs_err_pid7739.log分析日志参数，设置内存大于剩余物理内存

bin/catalina.sh 文件前面添加如下：

JAVA_OPTS="-XX:PermSize=128M -XX:MaxPermSize=256m -Xms512m -Xmx512m -Duser.timezone=Asia/Shanghai"

再启动就没报错信息了。
