Yes, it is normal and nothing to worry about. > Does the '1915M Inact' means "zombie memory" (non-returned)? No. 'Inact[ive]', 'Cache' and 'Free' can all be considered free memory in slighly different states. There are differences between them that can be important in some circumstances, but if you are just trying to determine if you have a memory leak somewhere they can be lumped together, > Is there a manual garbage collector i could run?
