The problem seems hard to reproduce though (we still have the same configuration in production without any new crash and we only had a total of 3 OSD crashes). I'll just say for reference that BTRFS with kernel 3.18.9 looks suspicious to me (from the events that happened to us on a mixed 3.18.9/4.0.5 cluster statistically there's about 80% chances that there's a BTRFS bug in 3.18.9 solved in 4.0.5).
