Thanks for your answer, yes, I tried 'gc()' it did not change the bahavior.

have you tried putting calls to 'gc' at the top of the first loop to make sure memory is reclaimed? You can print the call to 'gc' to see how fast it is growing.

Does somebody have an idea why this behaviour might occur? Note that all the objects (like 'DummyCatcher') are reused every cycle so that I would assume that the RAM used should stay about the same after the first 'chunk' cycle.
