Kea uses this configuration and assign address 192.168.51.50, but when I send 'get-config' to kea4 it sends back:

{
  "result": 1,
  "text": "Error during command processing: unknown DB access parameter: max-reconnect-tries=0"
}

and logs:

2018-11-07 08:02:00.045 INFO  [kea-dhcp4.commands/5027] COMMAND_RECEIVED Received command 'config-get'
2018-11-07 08:02:00.045 WARN  [kea-dhcp4.commands/5027] COMMAND_PROCESS_ERROR2 Error while processing command: unknown DB access parameter: max-reconnect-tries=0

When I checked logs from reconfiguration it looks like not everything went 100% correct:

2018-11-07 07:58:21.431 INFO  [kea-dhcp4.dhcpsrv/5027] DHCPSRV_CFGMGR_NEW_SUBNET4 a new subnet has been added to configuration: 192.168.51.0/24 with params: t1=1000, t2=2000, valid-lifetime=4000

Why values readonly=false reconnect-wait-time=0 tcp-keepalive=0 tcp-nodelay=true max-reconnect-tries=0 are added to memfile configuration?
