We have an issue, where once a host goes into a soft down state, the retry check runs quicker than the host setting. Our retry interval is set for 1 minute on all hosts. but when they go into a soft down state, the check retries anywhere from 29-39 seconds, when it should retry at 1 minute.

Here is a sampling of the soft down checks.

This is a similar issue to: https://support.nagios.com/forum/viewto ... =7&t=22249 but we never saw a resolution.

Thanks.

This could be a bug, seeing as a solution wasn't found with the past thread. I'd like to gather a bit more information about your system though -

How many hosts / service checks are running on your machine? How many CPUs are allocated to it? What's the load like on it?

As well, please post the output of the following-
Navigate to Admin -> Monitoring Engine Status, and Admin -> System Status - post a screenshot of both pages for us to take a look at.

Attached are the screenshots for top, Monitoring Engine status and System Status.

Let me know if you need any further information.

Nothing looks too crazy above. Can you post a complete definition for one of the hosts as well?

Here is the host config's for one of the Hosts. (Nothing out of the ordinary here.)

Can you please post the config for the host template 24x7-linux-server_event including other definitions used by this template such as time periods.

Also, can you find this host object in these files and post the details here please:
/usr/local/nagios/var/objects.cache
/usr/local/nagios/var/retention.dat

If you have a ramdisk implemented the objects.cache may not be in this location and you'll need to consult /usr/local/nagios/etc/nagios.cfg for it's location.

Attached is the server template, retention and cache information.

Rentention.cache

Do you have parent/child relationships set up, or predictive checks enabled?

https://assets.nagios.com/downloads/nag ... ility.html

Either of those might be causing things to be checked more often than they are configured to.

We do have Service Dependency checks setup. I'll remove the dependency checks and post the results after the next issue.
