I am running the built-in version on Snow Leopard. It reports that it is 2.2.14. If it is WO specific, the same app did not exhibit this behavior on another server.
I'm considering whether I could log every request the app generates and see if I can match up the request (or even the method that was run) with the time that the hung process was spawned? Or maybe httpd has some advanced logging that could tell me something.
Love to hear if anyone else has seen anything similar and how it got addressed.
Take a look at the min. spare servers, max spare servers, and num. servers to start. I keep these numbers low (10/10/10) to avoid old httpd processes. Theory is that a new connection gets a new, or not as old of an httpd server. My servers are not normal so YMMV. There is a lot of voodoo in deployments settings...
I can second Chuck's experience with Apache 1.3.
