Can you try disabling scrubbing and see if the leak stops?
ceph osd tell \* injectargs '--osd-scrub-load-threshold .01'
(that will work for 0.56.1, but is fixed in later versions, btw.) On
newer code,
ceph osd tell \* injectargs '--osd-scrub-min-interval 1000000'
ceph osd tell \* injectargs '--osd-scrub-max-interval 10000000'

Thanks!
