I meant like in general…

I do agree it’s worth investigating if it happens again. My best guess so far would be some kind of data written to a tmpfs. That’d explain it not being associated with a particular process, yet counting towards actual used RAM.

Why do you care so much about memory usage?

Unused RAM is wasted RAM.

You can use journalctl -b <index>, where 0 is the current boot session, -1 the previous boot session and so on.

You can see all sessions with journalctl --list-boots if you want to pick a specific one.

Oof…

I had kept MikroTik in mind for a source of good value networking equipment, since I’ve heard many good things a few years ago, but apparently this has been an ongoing issue?

I’ll need to do more research on this, but skimming this article I will probably avoid their products in the future.

Spacebar looks promising IMO.

That doesn’t match my personal experience at all.

Using the toilet with each other present has been a thing in every relationship I’ve been in. And no, at no point was that a kink of either one of us.
