Hi Thomas, Fixing memory consumption problems is hard, but important: memory efficient code is automatically faster in the long run as well.
Your issue sounds serious. However, I would start by trying to figure out what is happening at your coding level: somehow you (or something you use) must be holding on too much memory. Questioning low level memory management functionality should be the last resort, not the first. There is SpaceTally that you could use before and after running part of your code. Once something unexpected survives GC, there is the PointerFinder functionality (Inspector > Explore Pointers) to find what holds onto objects. But no matter what, it is hard. If you have some public code that you could share to demonstrate your problem, then we could try to help.
