Description
Since the upgrade to 14.2.10 I have multiple OSDs in our big cluster that are overconsuming memory and are being OOM killed. They have a target of 10G but are doing 30+. I have to restart the OSD process multiple days a day to avoid OOMs.
Never had this issue before.
I don't know how to give you more info, please suggest something and I'll provide.
