Hello everyone,
I have an issue with my desktop, which I really don’t understand.
It is a desktop PC, with a Nvidia GPU, which I use for development (of AI, but like the image analysis part, not the slop part). I usually let it always run, and my previous machine was working fine like this.
However, on this machine, I get crashes after either a few days or a few weeks.
These “crashes” are weird : the machine is still up (and I can ping it), however I can’t ssh into it, I can’t connect to cockpit either, and can’t login physically on it (the display is frozen).
The only way to get it back up is to forcefully shut it down, wait a little and then powr it back up; but this isn’t ideal, since it interrupts computations etc
The only crashes shown in journalctl are related to irrelevant (I believe) programs : KDEConnect, DrKronqi, etc; nothing right before the crash.
Do you have any idea what could cause this ?
I tried logging temperatures, but nothing abnormal showed up. I ran memtest86+, nothing showed up either. Smart tells me everything is alright for my drives as well.
Right now I’m thinking about changing the alimentation or the motherboard, but frankly I don’t know what’s going on and it’s really puzzling me.
i am going to follow this as i am having a similar issue (on multiple distros even and with nothing helpful in the journal either). i went as far as to replace the entire PC, suspecting a hardware issue (it was still under warranty) but the problem remained the same.
all i could find on the internet is it may be related to a combination of wayland and KDE plasma iirc. i deactivated stuff recommended by users and tried other suggestions but nothing ever resolved the issue. i have a feeling it has to do with certain updates after which the issue ebbs and flows but this might just be because the problem only occurs randomly in the first place, so this is an entirely “vibes based observation”.
my issue is definitely not an out of memory issue as i had btop open when it crashed and it showed memory usage of ~60%.
