We didn't update any packages on our ceph servers, they ran stable until these segfaults. Sometimes the OSDs recover by themselves, sometimes a whole host goes down and leaves a degraded cluster. The description in [2] sounds exactly like our issue ([1] is a duplicate of [2]). I'll spare you the details since the upstream bug has lots of information. There seems to be a backport [3] for Luminous, but it's still in progress although the change has been reviewed. I just wanted to raise awareness for this issue since it impacts our production cluster that ran stable for months and we'd appreciate it if the updated packages would be available soon to fix this issue. Please let me know if any further information is needed.
