HI Steven, This issue has been around mailing lists since the new version came out: https://lists.ceph.io/hyperkitty/list/ceph-users@ceph.io/thread/S5XBS63NFIBJHN44RQ4NES7F6GVIMH4T/
This is a new warning that can be adjusted or muted if uncomfortable but its advisable to check what’s causing this. We had a few warnings once upgraded to 19.2.2 and a single OSD restart vanished them away. Haven’t seen these warnings ever since.
