Hi Guys This is common error people get when they are using tomcat for big web application .so following are the steps to rectify this error : 1.0 click on tomcat start up 2.0 click on java tab in tomcat startup 3.0 Now add the following parameter in java option field :

-XX:MaxPermSize=512m -verbose:gc -XX:+PrintClassHistogram

4.0 assign intial pool memory 256 mb

5.0 assign maximum memory pool 1024mb

6.0 restart the server

This setting is applicable or this is an example when your system RAM is 2GB where the tomcat is running .

for other RAM size please make sure that memory division does not exceed to system memory.otherwise tomcat server will not restart.
