Nagios scheduled all service checks 24 hours ahead


Something very strange happened on my 2 nagios servers yesterday at 2300. All host and service checks stopped on both servers.
When i discovered it this morning, i found out that all service checks was scheduled 24 hours ahead ie next job was 2009-10-26 23:00.

Has anyone seen this problem before - Maybe this is an issue going back from dayligth saving time yesterday morning 0300.

Ny nagios installations is nagios core 3.2.0



I have also seen this on our 2 Nagios installations. Same version. All the last checks ran shortly before 23:00 last night and were all rescheduled to run at 23:00 tonight. Since I am certainly running a different configuration this must be a bug.


Hi all,

I also have the same problem.How can i re-schedule services and host ?. Is there any command for this action?




I solved the problem with

/etc/init.d/nagios stop
cd /usr/local/nagios/var
mv retention.dat retention.bak
/etc/init.d/nagios start



Hi petercal,

It works thank you.



Seeing the same problem on both our nagios installations, versions 3.1.0 and 3.1.2.

Tried to submit a bug report but I’m seeing their tracker as down…


I’m seeing the same on three different installs of 3.2.0. Happened the day after the ‘fall back’, so like petercal I’m guessing a DST bug.
