Re: [Nagios-users] Determining what is causing a high load reported by check_load plugin
In top, does it show the same load values? The status of your memory shouldn't cause the nagios plugin to report high cpu. What does the uptime command say? Try running the check_load script by hand on that host and verify it returns the same results.
