Hi,
if you check
ceph mgr module ls | jq -r '.always_on_modules[]'
you'll see that crash, orchestrator and other modules are always on
and can't be disabled. Without the pipe to jq you can see the whole
list which is a bit long to get just an overview.
Anyway, comparing your enabled modules you have diskprediction_local
enabled, can you disable it? Although I don't really expect this to be
the root cause.
And what about the hanging cephadm shell sessions, can you see them on
the hosts?
Do you see those shell sessions on the host(s)? I'm playing with a
pacific cluster and due to failing MONs I see a couple of lines like
these

Hi Eugen,
Here it is:
# ceph mgr module ls | jq -r '.enabled_modules[]'
cephadm
dashboard
diskprediction_local
iostat
prometheus
restful
Should "crash" and "orchestrator" be part on the list? Why would have they
disappeared in the first place?
Best regards,
Sebastian

Here the 'ceph osd tree' command didn't finish, so I stopped that pod.
Maybe that could help, at least worth a try.
