After setup the monitor and apply, I would get "Waiting for configuration verification" that took about 40 minutes. Looking at tha nagios.log file I saw tons of the following

[1490657671] wproc: Core Worker 27743: job 1199 (pid=20620): Dormant child reaped

What versions are you running?

Posted: **Tue Mar 28, 2017 1:28 pm**

Hi, it's Nagios XI 5.4.2

One thing I noticed is that http load is extremely high when the core manager is making update. After that's done, it's back to normal.

Can you login to the Nagios server in a shell and post the output?

Code: Select all

cd /usr/local/nagiosxi/scripts
su nagios
./reconfigure_nagios.sh

Running the reconfigure_nagios script is almost the same as running the Apply Config and we should be able to see the error and go from there.

That appears to have only taken 5 seconds, can you try applying config through the UI again?

Posted: **Tue Mar 28, 2017 6:06 pm**

Try apply the config again from UI, same deal. In fact, the node was in "almost" frozen state while this is taking place. Again, httpd was the culprit for high load.

Please run:

Code: Select all

# tail -F /usr/local/nagiosxi/var/cmdsubsys.log

Then do an apply config from the GUI. Cancel out of the tail, then please send the output generated.

Also please include the files /var/log/httpd/*error_log.

Posted: **Thu Mar 30, 2017 5:08 pm**

The /var/log/httpd/*error_log is empty

> ls -lrt *error_log
-rw-rw-rw- 1 root root 0 Feb 28 20:33 ssl_error_log

Applied the config and got the following,

Is this a new install? If so, you ***could*** run reset_defaults.sh (I've intentionally not given you the full path so you don't accidentally run it). Now, why did I highlight could? Well, it's a giant red reset button (neither literally a button nor red). It's not something you want to do lightly, but it might get back on track more quickly than the forum.

Another option would be to try to upgrade to 5.4.3: https://assets.nagios.com/downloads/nag ... nstall.pdf . Again, it's a bit of a sledgehammer approach, but we are over three days since your original post, so maybe it is time for the sledgehammer. The upgrade makes a lot more sense to me than the reset, but people have different rules about upgrading in their environment, so I've given both options.

Lastly, can you PM me your Profile? You can download it by going to Admin > System Config > System Profile and click the Download Profile button towards the top. If for whatever reason you *cannot* download the profile, please put the output of Show Profile in the thread (that will at least get us some info). This will give us a lot of logs all at once, which again, I hope would speed up a resolution for you.

After you PM the profile, please update this thread. Updating this thread is the only way for it to show back up on our dashboard.

EDIT: profile received
