client connections.
USERS AFFECTED:

PROBLEM DESCRIPTION:
IHS may stop responding then stop accepting no new connections.
ps output shows no request handling processes (with appx
ThreadsPerChild threads) are running, only utility daemons.

The code was fixed to properly count the number of "active
daemons" when children exit due to MaxRequestsPerChild.
