I have two servers load balanced running a large-load website (about 20 megabit each server)
one is running 4.4-STABLE other is 4.3-STABLE from about two months ago.
the apache binary is the same on both.
the 4.4 system over time the apache processes get HUGE until the system runs out of swap, and the 4.3 system stays small.

This is after about 20 minutes of running.  given 3-4 hours they will be about 10 megs each.

This is the 4.3 system after 1 hour of uptime:
