Then the question was brought up as to why these reserved segments aren't released when Apache is restarted. shm_* are script-level functions, and the methods you're talking about are engine-level functions. Now, PHP_MINIT() and its brethren aren't accesible from scripts, so there doesn't seem to be a way to do it within a script. My reasoning is that since it is an OS-level detail and scripts only get executed when you access their URI, then the scripts will never get a chance to release the segment when Apache is shut down. Maybe a fix would be to have some sort of web-server-level shared memory support as well. Most people don't need the OS-level stuff anyway for programs outside of the PHP engine; they just need something that can survive execution of the script. -- Ignacio Vazquez-Abrams <ignacio@openservices.net>
