When my book comes out it'll say just a little more. The vital question here is whether you have a proper understanding of Apache's hooks. Since it's you, I'll guess the answer is yes - or at least that it will be by the time you deploy something with the monitor hook. Be aware that it's very different to other hooks, and could be dangerous. The monitor hook runs periodically in the parent process. The original motivation for it was to support a "watchdog" module, that keeps watch on the scoreboard and kills any child processes that appear to be stuck in a state for longer than some max time. That saves the server from the worst efects of buggy applications, or could be used in the manner of ulimit to place limits on users of a hosting service. The conceptual gotcha is being in the parent process (which also means it'll run as root). The practical gotcha is that you need to take a lot more care over using the pool, or you'll get a memory leak (or worse). -- Nick Kew --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
