Hi Marek, It appears that kea-dhcp4. kea-dhcp6, and stork-agent were started multiple times. I do not know how you are starting the daemons but perhaps something changed with the startup process (systemd?) that caused the thing that is starting the daemons to not realize they are running, thusly starting them multiple times?
