KEA service stopping through the day

@w0w The notification text is as reported in the notification sent. Configuration-wise, I am running Kea services.

The watchdog package also thinks you are running 'dhcpd' ( ? ) :

13:54:00 Service Watchdog detected service dhcpd stopped. Restarting dhcpd (DHCP Service)

Check the watchdog settings, and remove any dhcpd references ?

@Gertjan Point taken on the DHCP (ISC) service and watchdog. I had not removed the ISC DCHP service from the watchdog when I switched to KEA. BUT, that alert was only triggering when the KEA DHCP v6 service failed, which it is still doing. New watchdog triggered a bit ago.

Notifications in this message: 1

12:11:00 Service Watchdog detected service kea-dhcp6 stopped. Restarting kea-dhcp6 (Kea DHCPv6 Server)

12:11:00

What is shown at that moment in the system log ? DHCP log ? Was the interface (LAN ?) disconnected ? System services restarted ?

bartkowski · Nov 13, 2023, 7:11 PM

I too have this issue.
Under "Services Status" - Kea DHCP service shows stopped. Starting it has no effect.
I already deleted the Watchdog entry for ISC DHCP as it was filling the system log with messages @bcdouglas posted.

System log for DHCP:

Is the file /tmp/kea4-ctrl-socket.lock still there? If so, if you remove it (e.g. rm /tmp/kea4-ctrl-socket.lock) and then restart Kea, does it start and stay running?

bartkowski · Nov 13, 2023, 8:07 PM

@jimp I ran the rm command without checking if the file still exists and then switched to Kea DHCP and the service is running now. I'll post if it stops again, but this is a good sign. Thank you.

If it happens again look back farther in the log for other errors. Something had to have made it fail and leave that lock file behind.

Though something should probably be cleanup up that socket lock to stop it from being blocked in the way you encountered.

EDIT: I created a Redmine issue for that problem case: https://redmine.pfsense.org/issues/14977

I've restarted kea on the dash board GUI, as it was signalled 'stopped'.
Take note at the end of 57958 : it failed , as 66699 is still running and doing its job.

66699 never died or someting like that.
There is no indication in the log file that the initial kea process 66699 actually received a 'stop' or 'kill' signal.

Curious. I wonder what the contents of /var/run/kea/kea-dhcp4.kea-dhcp4.pid were during that time.

I could maybe see something like that happening if the PID file in /var/run/kea/kea-dhcp4.kea-dhcp4.pid contained a PID that didn't match the daemon that was running.

Gertjan · Nov 14, 2023, 4:12 PM

@jimp

That's the one I'll be looking at - the content - the next time.

Cobrax2 · Dec 9, 2023, 6:03 AM

I switched to kea too, and it can't restart if it somehow gets hung or killed by unbound because of that lock file. Is there a way to add the rm command in the startup file of kea? What is the startup command for it, where is it located? I'd hate to have to run a cron job every minute just to remove it...
Thanks

My KEA service (in an HA setup with two pfSense instances, both 2.7.2) kept behaving oddly, so I reverted to the ISC DHCP server which so far has been 100% stable. I don't think KEA is ready for prime time yet. Here's what I've observed:

Once, I entered 10-15 static IP mappings, and the next day I noticed they were all gone.
KEA server sometimes ran OK on both HA nodes, sometimes it stopped on one node but not on the other
While adding static IP mappings today, I went back to edit a handful to enable Static ARP on the MASTER HA NODE. Reproduction steps:
** Click EDIT on a static DHCP rule.
** Click on static Arp checkbox to enable
** Hit Enter
** Go to Status -> DHCP Leases
** It's blank. The KEA Service on MASTER NODE had stopped itself with the error: "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"
** This was very reproducible
Also, when doing CARP failover, sometimes KEA would stop on one node and not run on both after I disabled the forced-failover

Again, wayyyyy too many issues.

SteveITS · Dec 21, 2023, 4:07 PM

@Markito said in KEA service stopping through the day:

sometimes ran OK on both HA nodes

https://docs.netgate.com/pfsense/en/latest/releases/23-09.html#kea-dhcp-server-feature-preview-now-available

"Currently the Kea implementation lacks the following DHCP server features:
... High Availability Failover"

Markito · Dec 21, 2023, 4:09 PM

@SteveITS Thanks :) I had not realized that.

ThomasDr · Jan 1, 2024, 5:07 AM

@w0w
This can happen if you have switched from dhcpd to kea but have not changed the service watchdog.

chudak · Jul 29, 2024, 2:33 PM

@jimp Today see TS state unexpected state: NoState and removing /tmp/kea4-ctrl-socket.lock does no help

something new?

marcosm · Nov 14, 2024, 7:19 PM

This issue should be handled with the 24.11-RC. Feedback on it would be helpful if you were hitting this previously.

darkrolder · Dec 8, 2024, 8:42 AM

@marcosm This issue is happening to me
a few nights prior i woke up to some "IOT" things flashing as they couldnt connect to their wifi.
and found i didnt have internet, however when i got up at 6 it was working again without user intervention so i am not sure..

this morning i woke up to no "internet"
(some statically set things over ethernet were working, obv) but everything wifi was offline.

on the router, kea ipv4 was offline i had to click the start button, for now i have installed the watch dog server to auto restart. id send logs if i knew where and which ones you wanted to help diag this? or if this is even related? (running 24.11)

best regards
