Hi, firstly - this monitoring ecosystem is great, thank you for this!

I prepairing single icinga monitor system in template virtual machine.
Once I was almost done, I was made a virtual machine copy to test in real world.

When I was change hostname I run into problems. Most of them I can trace and fix, but the last one is too deep inside. I have no idea.

Command from Inspect :

'/usr/lib/nagios/plugins/check_nrpe' '-A' '/etc/icinga2/pki/cert_nrpe/ca.pem' '-C' '/etc/icinga2/pki/cert_nrpe/cli.pem' '-H' '192.168.1.103' '-K' '/etc/icinga2/pki/cert_nrpe/cli.key' '-c' 'checkcpu' '-a' 'time=25m!!time=15s!!time=5!!crit=82%!!warn=60'
Command is created in director from external script.

The error come when service applying to host:
free(): double free detected in tcache 2
<Terminated by signal 6 (Aborted).>
What is most confusing - rendered comand by Inspect is working fine in cmd.

The same command work before I deleted old certificates and made new with icinga2 api setup

I don’t have any glue… 
Thank for any help.
              
Hi & welcome,
Trying it manually means executing as user root, but icinga executes the check as user nagios or icinga (depending on your distribution). For testing I always recommend to switch to icinga’s user first e.g.:
sudo -u nagios bash
and try i again you’ll get the same result as with icingaweb.
