Kea-dhcp dns registration high load

[netblues]

Latest plus 24.08 dev image.
Has been working for some time
Suddenly web console became very slow/can't login and eventually ened up to the crash screen.
Nothing to be reported though either on php or freebsd

On console I would see extremely high load running top
Lots of lockf processes and unblound-checkconf

Disabling dns registration and early dns registration solves the issue without having to kill processes

Have tried restarting, no change.

Has been working fine for some time, only change was enabling openvpn client registration.
I have switched that back to disabled, but the issue remains.

dhcpd.log also complaints

What else should I look at?

This has been resolved in internal snapshots

[netblues]

@cmcdonald Good to hear.
Any chances this to be an interim external release?

[cmcdonald]

@netblues an interim public snapshot would slow us down towards a GA release.

Soon.
