In all cases I compiled nrpe and the Nagios plugins 1.3.1 on the target machines. When I test check_nrpe to the openBSD system (eniac) the test times out, and the target system gets very busy (100% cpu) for a minute or so then returns to normal. I've turned on debug but there doesn't seem to be any errors in the logs. FAQs and Google searchs have come up empty as well. The RedHat7.2 system works beautifully. The plugins themselves work fine on the target system. Has anyone seen this before? Any ideas how to dig deeper into the issue? Some info that may help: Test command on nagios system: [root@Z3 root]# /usr/local/nagios/libexec/check_nrpe -H eniac -c check_load CHECK_NRPE: Socket timeout after 10 seconds.
