Kea memory leak (radius)

we have 2 kea servers (1.4.0 P1) that work with one mysql server as the lease database. host-cache + flex_id + radius hooks loaded. Only one server is active.

My Users are stable, About 1330 users and + 50 new users each day.

If I reload the kea-dhcp4 process the memory goes down to 0.4%. the host-cache fills up pretty fast to 1330 records, most of my users has lease "renew-timer": 200.

From that point the memory consumption rises about 3% each hour
