I don't believe there are any known memory leaks in apache httpd. But
it wouldn't be unusual for memory usage to increase somewhat over time
since some requests require more memory than others and it is usually
impossible to return memory to the OS. It shouldn't continue to rise
indefinitely. Memory leaks might be present in some module that you
using with apache.

You can, of course, recycle processes occasionally by setting
MaxRequestsPerChild to some not-too-small number.

Other than that, I'm not sure what question you are really asking.
