Also make sure that you are either using Stateless Working Memory or if you are using a Stateful Working Memory then make sure you're dereferencing objects. I had a similar issue and it turned out to be me using Stateful WM when I didn't realy need it and not dereferencing the objects. There are a number of tools around to help to identify memory leaks. JRockit has a pretty good tool for helping to isolate issues. That's how I isolated my issues. http://e-docs.bea.com/jrockit/docs142/userguide/memleak.html On Jan 7, 2008 3:27 PM, Michael Rhoden <mrhoden(a)franklinamerican.com&gt; wrote:

In 4.0.3, there is a memory leak with the use of WorkingMemoryLogger. Maybe it's that ?

Yes, and also 4.0.2 did had a memory leak that was fixed in 4.0.3, were no leak was detected my profiling tools. So make sure you are using 4.0.3.
