Description

We recently updated our cluster to 12.2.1. After that we moved OSDs on one of the nodes to Bluestore and since that we experience OOMs on that server on daily basis. We found #21417 so we disabled all scrubbing operations but it didn't help. We also installed there version with applied patch that was supposed to fix that bug, still, no change.

Dump of the mempools from OSD using currently over 3.3G of RAM included below.
Our ceph.conf also included below.
