Oops, I forgot to upload the journal fragment I was referring to. Here it is.

I did not bother to research at the time and did not see any reason as the problem did not manifest again . Then today, it happens again. The circumstances are similar: I leave the system long enough for the screen to power off and come back to find myself kicked out of my session. Yes, kicked out, not simply locked out. I need to log in again and find that all running apps and open files have all been closed. My journal would appear to show that gnome-shell got stopped as a consequence of systemd-oomd killing several applications (see the included journalctl snippet - mind that the output is in reverse order (journalctl -r)). Should not oomd terminate single applications instead of complete user sessions? And I do have some doubts about the statistics listed in the journal. One of the killed apps is reported as consuming over 22GB or RAM (out of 32). I have been using that app for many years and cannot remember having see it use more than a few GB.
