I wrote a basic python program to observe this memory leak. I see memory consumption is increasing %1.4 per day.

Another question i forgot to include in the original mail: Is there any point in trying to optimize a blocks performance by using OPEN MP or pthreads in cases of embarrasingly parallel operations? Or is it totally useless since all the cores are already at full load because there is one thread per
