What can I do? /rant: gnome-shell has always been this resource hog in the past few years, maybe after they started using JavaScript for almost everything. There are countless memory leaks that are being patched. 3.29 and 3.30 both have important fixes that are not in the 3.28 shipped by Red Hat for RHEL 7.6. > Basically - the machine isn't even doing anything.

But not out of memory. On workstations, I have to hit Alt-F2 and type "r" to restart gnome-shell every morning to keep its memory use at bay. For long running sessions, I'd switch away from GNOME. Maybe to Cinnamon, XFCE, or any other lightweight desktop environments. Fixing the memory leaks of gnome-shell is not trivial. -- Yan Li
