That's still the case. I have a test cluster consisting of 6 hosts, 66 osd

How many connections are maintained by randomly taken ceph-osd process?

On one prod cluster with 361 osds and ~36000 PGs, one container (one OSD per
container) manages around 3000 connections, host can have up to 12
containers, meaning 36000 connections per host.
