Again I tried to reproduce the observed memory growth with the example application (extended/hadronic/Hadr01) using the run time setup described in the thread, http://hypernews.slac.stanford.edu/HyperNews/geant4/get/hadronprocess/1214.html but failed to detect any noticeable symptom of direct memory leakage either in a visual monitoring (top) or in profiling with IgProf. Memory profiling results on a Linux system, AMD Opteron(tm) Processor 6136 were summarized at http://oink.fnal.gov/perfanalysis/g4p/g4p_9.5_Hadr01/index_igprof.html - please see the MEM_LIVE DIFF(100001-1) for a direct memory leakage; anything great than 100% under "Total %" indicate a direct memory leakage. The link also include the log file and the snapshot of the 'top' process of the application at the bottom of the page.

Since I have a similar conflicted result with the advanced/hadrontherapy example (assuming that the problem is not OS specific - Windows vs. Linux), it is now very difficult how to address this issue correctly. If we assume that reported problems (and my tests) are real, the problem may due to other facts (such as compiler, optimization flag and so forth). Before we investigate the issue further, it would be really nice if someone else can test these two applications (advanced/hadronherapy and extended/hadronic/Hadr01)independently and report behaviour of the memory comsumption in this thread.
