reacted not correctly in this situation and didn't complete key exchange with OSD's.

Today problem reappeared.
Restarting mon helps, but it is no solving the issue.
Is there any way how to debug that? Can I dump this keys from MON, from OSD or
other components? Can I debug key exchange?
Thank you

Hi all,
I have few problems on my cluster, that are maybe linked together and
now caused OSD down during pg repair.
First few notes about my cluster:
4 nodes, 15 OSDs installed on Luminous (no upgrade).
Replicated pools with 1 pool (pool 6) cached by ssd disks.
I don't detect any hardware
