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.
