Quenten, It has been noted before and I've seen a thread on the mailing list about it. In a long term, I've not noticed a great increase in ram. By that i mean that initially, right after doing the upgrade from emperor to firefly and restarting the odd servers I did notice about 20-25% more ram usage. However, it has been about a week since i've done the upgrade and according to my graphs, the memory usage has decreased and is now at about the same level as it was before the upgrade. It does sound strange, but that's the case with me. Here is my current usage on one of my odd servers: ps aux |grep ceph-osd root 23081 5.9 1.3 1889508 334908 ?

I upgraded from 0.72.2 to 80.3 now all of my Ceph servers are using about double the ram they used to. Only other significant change to our setup was a upgrade to Kernel 3.13.0-30-generic #55~precise1-Ubuntu SMP Any ideas?
