Uhm,

to be most correct... there was a follow-up even with version 0.56 ;)

Well,

subject seems familiar, version was 0.48.3 in the last mail.

Some more of the story. Before successful upgrade to latest bobtail everything with regards to scrubbing was disabled.
That is via:
    ceph osd tell \* injectargs '--osd-max-scrubs 0'

We are running fine now since 9th of may. Fine means though, not have ran any scrubbing for ages. This morning I re-started scrubbing. After a couple of hours I detected the first OSD's eating up memory. Top-scorer was running with 23GiB rss. After stopping scrubbing again there was no regain of memory.

Not anyone else with perhaps large pg's experiencing such behaviour?

Any advice on how to proceed?

Thnx in advance,

Oliver.
