For me it started late 3.9 if I remember right. But I'm pretty sure it startet with 3.10 which I mostly upgraded to for using skinny extents. While skinny extents has helped subjective performance a little bit I since experience the problem with ever increasing RAM usage - up to the point of 15 GB swap, full RAM, and almost none of it is used for caching. I wonder if there is a way to track where this "lost" memory is gone. Top shows no memory hogs. Slabtop shows some high numbers but nothing really impressive. It's just used for nothing it seems.
