Tomcat: Out Of Memory Exception

[Adalberto Toledo]

I have a problem, I'm using Tomcat 7.0.4 in JDK 1.6.0.22 web server to deploy my web application.

The problem after a day my tomcat says: "OutOfMemoryException: Java Heap Space", and the memory that I assigned is 500 MB in JAVA_OPTS and CATALINA_OPTS environments variables.

I'm using the Nio Protocol in my application because I need some comet procedures.

My server is ubuntu 10.04 LTS

If this was my problem I would be using the Tomcat management app to monitor Thread and memory use. Perhaps you will be able to see a pattern emerge.

For example, you might see some request threads that never complete a request.
