Hello Ceph-users,
Florian has been helping with some issues on our proof-of-concept
cluster, where we've been experiencing these issues. Thanks for the
replies so far. I wanted to jump in with some extra details.
All of our testing has been with scrubbing turned off, to remove that as
a fact
One additional detail, we also did filestore testing using Jewel and saw
substantially similar results to those on Kraken.

Does anyone have any suggestions as to what could possibly be causing
a regular pattern like this at such a low frequency
nce behaviors?
