memory leak
What's the reason for that question?
This means that they allocate memory for something, but forget to release it, or due to a bug it wasn't released.
No software what so ever can stop this i think.
Unless it will record everything the app does, and after closing it will release the stuff still open.
But anyways, no product of Macecraft can fix this.
I suggest to check which software is the leaker, and report this to the producer of that program.
