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’ve had similar issues when I ran out of system memory. It also didn’t leave any traces in the journaling program, but I think it did say something about it in
dmesg. Not sure though. But since you’re probably using the VRAM and not the RAM, maybe this isn’t it at all? Just spitballing.
