Hi,
May be a bit late now, but if you are adding additional capacity I

Hi Laurent,
Wow, that's excessive! I'd see if anyone else has any tricks first, but
if nothing else helps, running an OSD through valgrind with massif will
probably help pinpoint what's going on. Have you tweaked the recovery

Hi,
We lost a disk today in our ceph cluster so we added a new machine with
4 disks to replace the capacity and we activated straw1 tunable too
(we also tried straw2 but we quickly backed up this change).
During recovery OSD started crashing on all of our machines
the issue being OSD RAM usage th
