When I use 4.0.3 testing , more than 1000 drools' object was created ,these
can't be destroyed through GC,
So , I think memory leak is also exist in 4.0.3.
4.0.1 is normal and GC quickly excute.

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.
