Pre-fork. That's weird. I set MaxRequestPerChild to 100, ran ab -n 500 url and I can see workers being destroyed and created but I only see MINIT being called once on startup. As workers exit I see MSHUTDOWN but no corresponding MINIT. Just to be sure my log apparatus wasn't setup yet I wrote a message to stderr, flushed it and verified that it's in the Apache error_log. I'm pretty sure MINIT gets called on startup and MSHUTDOWN gets called every time a child exits. I used stock Apache 2.2.6 and PHP 5.2.5 with the standard Apache 2 build instructions [1] (although I did not compile php --with-mysql) on x86_64-redhat-linux.
