Rather then terminating Apache request yourself, you can use universal Apache configuration directives that allow you to restrict memory utilization of an Apache process.

Hmmm, the ones I looked at seemed to prohibit a process from growing above a certain size. Can you point me to them? I don't want to prohibit a process from using what it needs (to a point). I need simply need a child to terminate after it has gone above a certain threshold. We found that the norm for our applications was 10-15MB. Usage above that was the exception. Some applications (especially when they were generating cache that had gone stale) would need more for a brief period. I don't want to stop that.

I still think your best bet is to simply allow for the top watermark for each of your processes and configure your machines with enough ram to handle perhaps a smaller number of processes. Or fix your code to use less if that high watermark is too high. Killing processes seems like a very crude fix here. -Rasmus
