To test this, I built a MacPPC app (20MB memory allocation, dynamic memory allocation tested both checked and unchecked) whose main routine saves 100 images to jpegs. Each time it runs that routine, the app grabs 15MB more RAM, until eventually it has allocated about 150MB to itself. It always crashes when the Mac's free RAM drops below 125MB. (I.1.1, MacOS 9.1, 512MB physical RAM)

Yes, if you continually allocate new resources, you will eventually run out of memory. If you reuse resources, or delete old ones and create new ones, your memory use should hover around a certain amount. So it depends on how your code is written. Can you post the code you're using?
