Accidentaly I checked one of my upgraded maas installations and found that it stops leacking two weeks ago, after another one OOM-kill. Between last two restarts there was 2 unnatended upgrades:
1. linux kernel from 5.4.0.150.148 to 5.4.0.152.149 and libx11-6 from 2:1.6.9-2ubuntu1.2 to 2:1.6.9-2ubuntu1.5
2. bind9 from 1:9.16.1-0ubuntu2.12 to 1:9.16.1-0ubuntu2.15
Looks like it was one of them, but I can't figure out, which one
