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.

To: "Rules Users List" <[email protected]> Message-ID: <[email protected]> Content-Type: text/plain; charset="iso-8859-1" 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.
