Definitely check the logs to see what was being requested at the time. Sometimes a search bot finds it's way into dynamic pages and goes crazy, but you could also have something that is being exploited to crash Apache and create a denial of service or worse. If you are running an out-of-date version of Apache or PHP or anything else that is being handled by Apache, it's probably time to upgrade. You might also have a memory leak somewhere in your code, or a "forever" loop that traps the server process in an unending cycle. Do you have some way of watching/logging memory usage? Setting MaxRequestsPerChild to a low value can be a temporary workaround for memory-related issues, at the expense of overall performance.
