However, looking at it in the Activity Monitor, the real memory used starts off at 25 MB and steadily grows to 250+ MB while the virtual memory starts off at about the same and steadily grows to about the same or sometimes close to 500MB, over the course of several minutes. This especially happens if I don't move the mouse for a while, or don't have the application in focus. As soon as a move the mouse or bring the application into focus, it's as if an autorelease pool is drained and the memory drops back down to 30-40MB real and 30-40MB virtual. This is annoying since the application hangs for 5 seconds or so when this memory draining is occurring. Has anyone dealt with this before? Any ideas on what could be causing this and how to work around it?
You're correct that it's an autorelease pool draining. Cocoa only
drains autorelease pools when an event is processed, and what it
counts as an event is not necessarily what you count as an event.
Some more info, and a possible fix, here:
