Hi, just curious, is that resource starvation caused by something big, e.g. a browser, using too much memory which leads to the kernel reclaiming also pages of program text sections because they can be reloaded from disk at any time, however those pages are needed again immediately after when some CPU core switches process context, leading to something that looks like a hard freeze to a user, while the kernel is furiously loading pages from disk just to drop them again, and can take from minutes to hours before any progress is visible? It has happened to me on Fedora in the past. I could probably dig up discussions about the problem in general if you want, they explain it better than I ever could. Does Fedora prevent that situation by tuning some kernel knobs nowadays for desktops? Thanks, pq
