We're also seeing unusually high mgr CPU usage on some setups, the only thing they have in common seem to > 300 OSDs. Threads using the CPU are "mgr-fin" and and "ms_dispatch" Paul -- Paul Emmerich Looking for help with your Ceph cluster?

That's how we noticed it too. Our graphs went silent after the upgrade completed. Is your large cluster over 350 OSDs?
A 'me too' on this - graphs have gone quiet, and mgr is using 100% CPU. This happened when we grew our 14.2.5 cluster from 328 to 436 OSDs.
