Hi, Yesterday I finally updated our cluster to emperor (lastest stable commit) and what's fairly apparent is a much higher RAM usage on the OSD: http://i.imgur.com/qw9iKSV.png Has anyone noticed the same ? I mean 25% sudden increase in the idle ram usage is hard to ignore ... Those OSD are pretty much entirely dedicated to RGW data pools FWIW. Cheers, Sylvain
