Mark you can even leave out the ifelapsed keyword. It is not in my config
files. It is just the default one. My point is that cfexecd must start
cfagent once in a five minute interval and not 5 times. I know i can set
Iflapsed to 5 minutes and let cfagent handle the locking, but i prefer
that cfexecd will do this for me.
