[Bug 63687] High Memory usage after upgrade to 2.4.41
https://bz.apache.org/bugzilla/show_bug.cgi?id=63687

Not now. I am honestly a bit lost now. It looks like that your processes
consume a lot of memory (about 600 MB) from the start due to their
configuration, but from pool usage perspective not much changes between the
freshly started process and the one which consumes the huge amount of memory
(roughly 2.8 GB). So the question is where is this memory lost and why did the
behavior change with the httpd version.
It could be that a 3rd party module consumes memory outside the pools, but due
to sideeffects introduced by the newer httpd version does not free up that
memory any longer or it is caused by the underlying memory management of the c
library, but then it should show up the same way with both httpd version. So
this is the rather unlikely option. Maybe we are left to the proposal from Joe:
Have a fresh process handle some requests to "warm up" a little bit memory wise
and then do https://bz.apache.org/bugzilla/show_bug.cgi?id=63687#c62 with that
process and see where it stops over and over again.
