If Apache is still responding, you can get an overview of this by requesting the server-status page (if you have mod_status enabled): lynx http://127.0.0.1/server-status If Apache is not responding, I've written a tool which might help you find out what is going on: http://fabletech.com/ftasv This tool can easily be run from cron to log activity at regular intervals.
