Peter,
thanks for the quick reply. please let me know if there is more detail
needed. i run Kea with ERROR level logging, so if more verbose logs are
needed, i would need to set up some time to test and collect the logs, etc.
the logs from the testing i did, as collected by my syslog receiver:

during query (error code: 2013). kea-dhcp4 862433
the database is a 3 node multi-provider MariaDB footprint, with Galera
(block-level) replication, all behind an HAProxy VIP. there are no
issues with the database being available. i tried a couple of times and
had to adjust a couple of IP/port combos because of the HA+MT config,
plus the Stork agent. thats why there are a couple "could not bind to
address, already in use" errors. once i got the Kea instances started,
no device would come up with a new lease.
my pretty printed config, from one of the Kea servers:
