Hi guys! I have a rather beefy machine. AMD Ryzen 7700, 32GB DDR5, GPU 7800XT 16GB, several NVME drives for OS, general data, games. And yet…after a while it becomes completely unresponsive. Mouse freezes, keyboard doesn’t key anything, and the screen gets completely frozen. Meanwhile the disk led gets full activity, almost constantly red. So…While this might be crazy pagination turning the system to a crawl (I have an 8GB swapfile), I want to be able to determine what’s going on. Is there a way I can check any log, or enable any kind of logging that would tell me what happened on the seconds before it became completely unresponsive? Who takes all my memory??
Normal situations where this happens:
Firefox open, multiple windows, lots of tabs. Maybe ~5-8GB of RAM.
Virtmanager running a Windows VM, running a work remote desktop…4GB of RAM
Steam…1GB of RAM
Thunderbird, Deluge, Telegram, Whatsapp…Not much more really.
This shouldn’t even come close to the RAM capacity of this machine. And yet…it really looks like it suffocates without memory. How can I check for issues?
Ok so I kinda had a similar problem. Difference is that I was using Arch and full disk encryption. System would freeze up if I tried writing big files and disk light would start blinking. It might not be that to so maybe run “journalctl -b -1” the next boot after your system freezes and check towards the bottom of the log to see if there are any errors, usually red. Another way is to use btop running in the background and when the system gives any sign that it’ll freeze switch to btop and check what’s going on. Edit: something that came to me is to try to switch to another tty using Ctrl+alt+number, I’m not sure how neon works so try 2 or 3 or 4.
