We have the same problem. I believe my code is squeaky clean but each
Apache process's unique pages count increases with time. Still, 10kb/100req
isn't all that bad.
Make use of MaxRequestsPerChild. At a rate of 500, you will still win on
the reduced overhead and not have Apache processes that grow out of control.
I scoffed at the idea when I first heard it, but was much happier to
consider it after I reached my wits end. It works nicely with that
variable set, so I'll leave it at that.
(I'm not sure this is even a code problem. Maybe perl is just bad at keeping
a single consistent working set and the copy-on write from the parent Apache
kicks in and keeps increasing unique per process memory consumption).
