My production Oboto 11.0.10 (standard Apache installation, no Docker is used) sends me an error every 10 minutes:

<h1>Details</h1>
Otobo Version=10.0.10
ITSMCore Version=11.0.8
The manual run of the EscalationCheck (./bin/otobo.Console.pl Maint::Ticket::EscalationCheck) shows no errors.
Before reporting the bug, I have drop the cache and rebuild the config:

bin/otobo.Console.pl Maint::Cache::Delete
bin/otobo.Console.pl Maint::Config::Rebuild

and also rebooted the server.

After the daemon restart the problem disappears for about 20 minutes, then reappears.

Hi Dmytro,

did you install and maybe uninstall any ITSM-related packages, like ITSMConfigurationManagement?

Maybe there is an error and they need reinstallation?

Please check your package manager.

All the best.
