Hi Eugen,
looks like this isn't [1] but rather
https://tracker.ceph.com/issues/38049
and
https://tracker.ceph.com/issues/36541 (=
https://tracker.ceph.com/issues/36638 for luminous)
Hence it's not fixed in 12.2.10, target release is 12.2.11
Also please note the patch allows to avoid new occurrences for the
issue. But there some chances that inconsistencies caused by it earlier
are still present in DB. And assertion might still happen (hopefully
with less frequency).
So could you please run fsck for OSDs that were broken once and share
the results?
Then we can decide if it makes sense to proceed with the repair.
Thanks,
Igor

Hi list,
I found this thread [1] about crashing SSD OSDs, although that was
about an upgrade to 12.2.7, we just hit (probably) the same issue
after our update to 12.2.10 two days ago in a production cluster.
Just half an hour ago I saw one OSD (SSD) crashing (for the first time):
2019-02-07 13:02:07.682178 mon.host1 mon.0 <IP>:6789/0 109754 :
cluster [INF] osd.10 failed (root=default,host=host1) (connection
refused reported by osd.20)
2019-02-07 13:02:08.623828 mon.host1 mon.0 <IP>:6789/0 109771 :
cluster [WRN] Health check failed: 1 osds down (OSD_DOWN)
One minute later, the OSD was back online.
This is the stack trace reported in syslog:

Is there anything we can do about this? The issue in [1] doesn't seem
to be resolved, yet. Debug logging is not enabled, so I don't have
more detailed information except the full stack trace from the OSD
log. Any help is appreciated!
Regards,
Eugen
