Stefan, What version of Stork are you using? I saw a similar issue<https://gitlab.isc.org/isc-projects/stork/-/issues/792> in 1.7.
Do your Kea control agent logs show any issues during the event?

Do not click any links or attachments unless you have verified the sender. We see this in the stork events every few days: 2023-06-20 20:01:23 daemon [2] dhcp4 is unreachable 2023-06-20 20:01:07 Communication with daemon [2] dhcp4 of app [email protected] failed After a restart of both dhcp4 and stork-agent on that adc1-server things work again. I will have to check the logs in more detail, sure. 2 things: 1) we collect the prometheus metrics from stork and visualize them in Grafana. storkserver_auth_unreachable_machine_total{instance=~"$instance"} is always 0, even when the mentioned events are seen and I would assume that one of 2 machines should be marked unreachable. Right? 2) it's not solving the problem at the root, but I consider setting up some external monitoring to detect this outage and let the monitoring restart the daemons ... I use monit (https://mmonit.com/wiki/Monit/ConfigurationExamples) for such things, and think of letting it do http-API-calls to isc-kea to check things. Right approach? thanks, Stefan -- ISC funds the development of this software with paid support subscriptions. Contact us at https://www.isc.org/contact/ for more information.
