memory usage

[Russell Scibetti]

I had a similar issue that I just solved.  Try reducing the 
service_reaper_frequency.  It detemines how often the parent nagios 
daemon collects the results of all the plugins.  If you have that many 
plugins at small interval, you could be writing too much for the pipe to 
handle.  Change the default service_reaper_frequency from 10 to 5 for 
started.  The daemon will reap the plugins' output more often, which 
should free up memory.
