From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

smartctl would be what your looking for even for ssds (although ssds fail quick enough that if smartctl catches something there's a chance it's already too late, smartd allows for scheduled tests and I've definitely saved data off of ssds because I had daily smart tests running that caught early failure).
I however strongly disagree with the hardware issue. there is no indication that this is hardware (honestly hardware accounts for VERY few issues like this, and RAM failing still happens but is 98% a thing of the past). diagnosing without any logs is a bit of a lost cause, we simply don't have enough info, hopefully OP updates the post with the output of journalctl from the last boot.
Bad RAM is still a thing (even on regular PCs), there's a reason ECC memory has a market (true ECC, not the stuff that DDR5 has built-in). But I agree that it's likely just an OOM/Thrashing situation. Linux famously doesn't handle them very well, and the behavior OP is seeing is very much consistent with that.
dead ram definitely still happens, yes, but it's exceedingly rare. I fix hundreds of PCs a year, and I maybe get one or two a year where the root cause is actually bad ram. more often it's configuration issues or hardware implementation issues, for example the gigabyte x870 boards really don't like XMP for some reason.
ecc doesn't really have anything to do with whether a ram stick fails or not, it can help with misbehaving sticks but if a stick is dead it's dead and ecc can't help a dead region.
