Hello,
whenever I restart osd.0 I see a pair of messages like

wrongly marked me down or wrong addr
a couple of times. The situation stabilizes in a normal state after about two
minutes.
Should I worry about this? Maybe the first message is about the just killed
OSD, and the second comes from the new incarnation, and this is completely
normal? This is Ceph 0.41.
It's not normal. Wido was seeing something similar, I think. I suspect
the problem is that during startup ceph-osd just busy, but the heartbeat
code is such that it's not supposed to miss them.
I haven't seen the wrongly marked me down messages, I'm just seeing that
'pairs' of OSD's are marking the other down.
Still trying to figure that one out.
Can you reproduce this with 'debug ms = 1'?
