Getting load warnings when load OK

[indy500]

Each day when our app server is working a batch nagios sends load warnings out even though they have been configured for much higher loads than the system experiences. Why am being alerted for loads well below the threshold?

Relevent /etc/nagios/nrpe.cfg line on monitored host:
command[check_load]=/usr/lib/nagios/plugins/check_load -w 16,10,4 -c 32,24,20

sar output from host at time of warning:

Could maybe be a float vs integer issue. What happens when you enter the thresholds as floats?

-w 16.0,10.0,4.0 -c 32.0,24.0,20.0

Changed command to add float values. WIll see what happens.

nrpe.cfg:command[check_load]=/usr/lib/nagios/plugins/check_load -w 2.0,1.5,1.0 -c 10.0,5.0,3.0

Thanks for the response.
