My wife and I are both running Mageia 7 64-bit with latest updates. She first started seeing the issue a month or so ago and I started seeing it a bit later (suspect I was later installing an update).
If multiple users are logged in via the display manager (using the Switch Users capability), a session will spontaneously close with nothing apparent via dmesg or journalctl (the logs suggest the user just logged out, but there are not the usual PAM logout messages until after the display server has already stopped). It may be the first session or a later one.
I was getting SMART errors on the primary disk on my machine so had suspected that may be related. However, the same problem is occurring having replaced the disk.
The only possible clue I can see in the logs is that acpid seems to always run in the same second the problem occurs and just before it, but it runs most of the time with no issue so this may be a red herring.
One machine is a Dell Wyse using Xfce and the other an HP EliteBook using Plasma. Both are using SDDM as display manager. Both have 8G of RAM and there is no evidence of being anywhere near full memory use when the problem occurs. All very puzzling!
