I have a program which does: for ( all pids ) for all memory regions (via mach_vm_region_recurse) remember object_id and pages_resident The problem: The sum (over all object_ids) of pages_resident is larger than what Activity Monitor shows as "Used:". Often it is larger than the physical ram in my computer. (Note: object_ids used by several pids are counted only once). Maybe my program has a bug - or I am misunderstanding what pages_resident is about. Could someone please enlighten me? Kind regards, Gerriet. _______________________________________________ Do not post admin requests to the list. They will be ignored.
