There is a Java Struts application running on Tomcat, that have some memory errors. Sometimes it becomes slowly and hoard all of the memory of Tomcat, until it crashes.

I know how to find and repair “normal code errors”, using tests, debugging, etc, but I don’t know how to deal with memory errors (How can I reproduce? How can I test? What are the places of code where is more common create a memory error? ).

In one question: Where can I start? Thanks

EDIT:

A snapshot sended by the IT Department (I haven’t direct access to the production application)

    Use one of the many “profilers”. They hook into the JVM and can tell you things like how many new objects are being created per second, and what type they are etc.

    Here’s just one of many: http://www.ej-technologies.com/products/jprofiler/overview.html
    I’ve used this one and it’s OK.
