Memory Leak Errors in Application server Logs

jponnu

Hi All,

I am getting Memory Leak Error in Tomcat Log frequently. We are not using any JSR Portlet, we are using Portal+WEM only.

Can you please help to resolve this issue.

This is the message you should get only when you shutdown tomcat. This is a new feature of tomcat since v6, and is harmless and can be ignored.
