Hi there

Anybody else experiment hight memory usage in Proxmox CEPH Storage Server?
I have a 6 node PVE CEPH and after upgrade, I have noticed this high memory
usage...
All server has 16GB of ram. I know this is not recomended, but that what I
have at the moment.
In fact, just 3 servers ran with about 90% of memory usage.
All server is IBM x3200 m2 with SATA disks...
Here's ceph osd tree
