Multiple daemon processes?

[Kevin Freels]

Still fighting this one. I was able to put a temp fix in the
/etc/init.d/nagios script to do a killall of the nagios processes which
at least addresses the problem with making sure everything is no longer
running when the "stop" is executed. However, the second daemon process
is still being started as the parent of all the subprocesses, while the
first one seems to be only for marking the pid (which it doesn't really
do).

Any ideas are greatly appreciated!
