Description
If for some reason the Kea control socket lock file is present while Kea is stopped, then Kea can never start until that file is removed.
Attempting to start Kea while /tmp/kea4-ctrl-socket.lock exists, even if Kea is not currently running, results in a fatal error preventing Kea from running:
Nov 13 13:07:53 kea-dhcp4 32826 ERROR [kea-dhcp4.dhcp4.0x1c655d812000] DHCP4_INIT_FAIL failed to initialize Kea server: configuration error using file '/usr/local/etc/kea/kea-dhcp4.conf': cannot lock socket lockfile, /tmp/kea4-ctrl-socket.lock, : Resource temporarily unavailable
Removing the socket file allows Kea to start (rm /tmp/kea4-ctrl-socket.lock).

I just experienced exactly this same problem:
DHCP4_CONFIG_LOAD_FAIL configuration error using file: /usr/local/etc/kea/kea-dhcp4.conf, reason: cannot lock socket lockfile, /tmp/kea4-ctrl-socket.lock, : Resource temporarily unavailable

I can't reproduce this at all on current snapshots. I've killed the process and left the old file in place, killed it and made a file owned by another user, killed it and made a file with invalid permissions, and so on. Every time it starts right back up perfectly. I've tried restarting the process by save/apply, by using the service controls, and so on. I even killed it, left the lock in place, and rebooted. Every time it starts right up.
It's possible they fixed it upstream or something else changed that made it a non-issue.

This issue was occurring for me too, and I have found a resolution. It manifests itself as a "ghost" kea process which is not logging, or visible to keactrl.

I checked Service Watchdog configuration and could see both dhcpd AND kea-dhcpd4 as actively monitored!
Once I REMOVED dhcpd from Service Watchdog, the repeated stop and start of the kea-dhcp4 service was resolved. So could the bug be fixed by checking to remove "dhcpd" from Service Watchdog when a user transitions dhcp configuration from ISC DHCP (Deprecated) to Kea DHCP?

I have experienced the same problem today 2 days after updating to 24.03-RELEASE
In addition to all described above, it seems that TailScale service was messed up as well, after the kea failure.
This bug seems alive

Any hints as to what might have led to it being in the broken state? I tried all manner of killing/crashing it and even making dummy lock files but I can't make it fail here now.

No. I managed to restore both DHCP and TS to a good state by switching "Kea DHCP" to "ISC DHCP (Deprecated)" back and forth and now both seem happy. No clue what caused the failure
Updated by Dean Arnold 4 days ago
I just switched to kea and am seeing the service get marked as stopped while the process is still running. Same socket error.
This has happened a number of times today, but I just reproduced it when disabling IPV6 on my WAN, although note this appears to be just one circumstance under which this issue occurs.
