This was configuration problem in host reservations, sorry everyone

> Initial forward and reverse DNSUPDATE commands succeed:
> DHCP_DDNS_ADD_SUCCEEDED DHCP_DDNS Request ID xxx: successfully added
> the DNS mapping addition for this request: Type: 0 (CHG_ADD)
> But Kea does another CHG_ADD only a minute later and it fails:
> port:5353, rejected a DNS update request to replace the
> address mapping for FQDN, wkst7.lan., with an RCODE: 8
> DHCP_DDNS_ADD_FAILED DHCP_DDNS Request ID yyy: Transaction outcome
> Status: Failed, Event: UPDATE_FAILED_EVT,  Forward change: failed,
> Reverse change: failed,  request: Type: 0 (CHG_ADD)
> Is this a problem or can it be ignored? Is it due to setting
> "override-no-update": true and "override-client-update": true?
