Hello, I want to thank you to post your result of your test as I have the same problem as you since one year. I have a NUCPRO12 with the SSD Samsung 990 pro as my system disk. About once a month since one year (it's very random) , my server crashes unexpectedly. The crashes are often accompanied by a flurry of I/O errors, EXT4-fs error, Buffer I/O error on dev dm-0 and out-of-memory (OOM) killer messages, indicating severe issues. I primarily use the server for containerization (running Docker containers) and Plex for media streaming. What I've Tried: fsck: Verified all partitions with fsck, and they are reported as clean. smartctl : I ran smartctl on the system disk, and no errors were found. The disk is relatively new (1 year). Memory Upgrade: I upgraded the RAM from 16GB(2x8) to 32GB(2x16) even though my previous setup never exceeded 40% of its memory usage. I’ve already cleaned the RAM, re-seated the disks, and ensured everything is properly connected, but the issue persists. Post-crash log issue: After I reboot the server following a crash, I’ve noticed there’s a gap in the logs. It seems like no logs are recorded from the moment of the crash until the server is rebooted, making it difficult to diagnose the exact cause. I juste ordered an enclosure to test if the problem go away or not. I'm not on Unraid though , I'm on Ubuntu 22.04 with kernel generic 5.15. I could upgrade the kernel too , but not sure it will resolve this issue. I hope to resolve this with the enclosure, I'll post it here when after my tests !
