Hello,

During testing of G4 8.1 such leak was not observed. A simple test may be 
if you substitute QGSP by LHEP Physics List - is leak there or not? If 
will not disappear, likely problem is inside your application.

Another possibility is a non-standard computing platform (OS, compiler,
CLHEP...) - if it very different from our "official" variant, which were 
well tested.
