Does the code just hang, that is keep running but not print anything. > Is it possible that the method goes to inifite loop? This is not suppose to be possible. > Is there any parameter to avoid this situation? You need to determine what it is “hanging” on. Try running with -start_in_debugger and when it “hangs” hit control C and type where to determine where it is.
