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"

1500 OSDs, mgr is constant %100 after upgrading from 14.2.2 to 14.2.5.

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.
