It may or may not be relevant, but I've seen the message

kea: ERROR [kea-dhcp4.dhcpsrv]
DHCPSRV_MEMFILE_LFC_UNREGISTER_TIMER_FAILED failed to unregister timer
'memfile-lfc': unable to unregister non existing timer 'memfile-lfc'

in the past.   Could the lack of a timer be the reason I don't see LFC run?

I posted a message about it here:

https://lists.isc.org/pipermail/kea-users/2016-February/000228.html

but two replies later, I got the comment back:

===
At the very brief glance this issue is mostly harmless. The issue is
about failure to unregister a timer. Since the server is being shut
down, the timer will not triggered anyway.

Which I thought was a bit odd because there was no curiosity about the
reason why a timer that should be running was not running.
