[rules-users] Drools 4.02 or 4.03 memory leak?

[DELBART Vincent]

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.

	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.
