Every memory hungry program is concerned; and yes: it happens exactly on exit. > it's because the program is writted the way it's doing a lot of things > (probably unneeded) on exit. Have a look at what happens during exit: /usr/src/sys/kern/kern_exit.c:exit1() especially at the call to vm_waitproc(): /usr/src/sys/vm/vm_glue.c:vm_waitproc which calls vmspace_exitfree(): /usr/src/sys/vm/vm_map.c:vmspace_exitfree() Now, vmspace_exit() and vmspace_exitfree() ultimately call: /usr/src/sys/vm/vm_map.c:vmspace_dofree() It then goes deep into the bowels of vm amd pmap, and that's the place where the pages are paged in again (I think). > not exit(2) itself -cpghost. -- Cordula's Web. http://www.cordula.ws/ _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
