You have some interesting choices with your settings.  If you have the  
freshness and the reaper_frequency set to the same time of 60  
seconds.The freshness threshold is the time in which Nagios should  
consider a check to be stale.  This is done by looking at the last  
check's timestamp and comparing it to the threshold you set (60  
seconds).  While the reaper_frequency is the frequency in which Nagios  
will take all the collected passive results and process them, which  
you also have set at 60 seconds.  You are setting up a condition where  
most of your checks are running close to stale and, given any  
processing time, with give you many stale results.

Depending on your how powerful your system is, you will need to either  
increase your freshness threshold (try 300 seconds), decrease the  
reaper frequency, or do both.  You may have to play around with the  
exact settings that will work with your system and the number of  
checks you are performing.  I would recommend you start with  
increasing the freshness threshold.

Good Luck!
