	The thing to do is to try to figure out whether the problem is 
being caused by cfengine or syslog-ng.

	First, try logging some other command in exactly the same way. 
Probably the best way to do this would be to add something else to the 
"program" bit in f_cfengine (but I don't use syslog-ng, so I'm just 
guessing).  If you are also getting duplicates for these, then you should 
contact the syslog-ng mailing list, as they will be the people best able 
to help you.

	If there are no duplicates there, try logging cfengine locally 
(but still via syslog-ng) and see if it still produces duplicates.  Let us 
know the results of this, and we'll see if we can help.

        :)
