Ceph x daemons have recently crashed

Since last Ceph update (to current 17.2.5) we noted that every node reboot will mark OSDs from that node as crashed. However they return with the server boot normally.

I checked ceph and journalctl logs, and I did not find anything relevant about the daemons crashing (timeout, segfault, etc)

Is this something normal after the reboot (the CEPH HEALTH_WARN)? Seems not, because this is new for us.
