Anyone ... thought I'd go back to this. Does anyone have any ideas why I would get the following in the Nagios logs: nagios-03-10-2012-00.log:[1331336760] Warning: Check of service 'DEAL SERVER SERVICE TCP 4099' on host 'TDUKUBS01' could not be rescheduled properly. Scheduling check for next week... nagios-03-10-2012-00.log:[1331336760] Warning: Check of service 'DEAL SERVER SERVICE TCP 4099' on host 'TDUKUBS02' could not be rescheduled properly. Scheduling check for next week... As mentioed below, I've checked the config multiple times, I run 1100+ service checks across 100+ hosts and just these two are causing a problem - they differ in that they have specific time periods defined - all detailed below. I've checked the various reports that NTP is at fault but it made no difference at all. <img src=cid:_1_0A555A680A55565C003A1BE7802579C2> And if I force a check, it works and then schedules to run again tonight at 23:46 when I want the time period to begin: <img src=cid:_1_0A5568940A5565C4003A1BE7802579C2> Thanks - Julian.

Lots of mentions of NTPD and it should be fixed / still doesn't work. And in my case whether I enable NTPD or not makes no difference. My checks for specific hosts are still getting rescheduled for next week. I run multiple Nagios instances and its only affecting this one - and annoyingly these checks are some of the most important but just happen to need to run at specific times of the day. Any other help / ideas would be appreciated. Thanks - J.
