Thank you for all your suggestions. I did not wait till getting out of memory. I analyzed heap dumps continuous and find keeps on increasing the objects and also taking more memory so I stopped after half an hour. I want to know why StandardSessions are increasing. It is not happening in tomcat 5.5.28. See the attached image for the finding out what taking more memory. http://www.nabble.com/file/p25883072/Tomcat6.0.20-heap-analysis.png
