I have to believe it is daylight savings time related. My fix is to go click on each service one by one and reschedule. Then they start checking normally again. I wonder if there is anyway to force an automatic reschedule of all services and hosts for next year when this happens again?

Then suddenly, all services on all hosts except one stopped checking. The next scheduled check is about 24 hours from the last check. I had been checking every 5 minutes. Restarting nagios didn't help. I am using a gui NagioSQL to edit my configuration files so I suspect it did something to me but I have no clue where to look except where I have already looked. What can cause nagios to just stop checking everything like that or to randomly switch to every 24 hours rather than the configured every 5 minutes? I am having to manually do force checks to get it to check. Here are some things I have checked... Hosts check_interval is 5, retry_interval is 1 Services check_interval is 10, retry_interval is 2 So where could Nagios be getting the idea that it is suppose to be every 24 hours? </blockquote> I had the same experience yesterday. Maybe daylight savings related? At about 11pm, all the services were scheduled for 11pm the following day. I figured it was something I did wrong. I noticed that "next_check" time in /var/log/nagios/retention.dat was wrong. I renamed the file and restarted nagios. It worked fine after that. I using version 3.2.
