Use this task to start the lightweight memory leak detection using
the Performance and Diagnostic Advisor.
Before you begin
If you have a memory leak and want to confirm the leak, or you want
to automatically generate heap dumps on Java virtual machines (JVM) in WebSphere
Application Server, consider changing your minimum and maximum heap sizes
to be equal. This change provides the memory leak detection more time for
reliable diagnosis.
