November 27, 20241 yr have a couple of systems running Unraid for quite a while. My home machine is quite large and works well most of the time. Lately, it has started freezing up due to CPU and memory overflow. I pulled a diagnostic today, and it showed CPU and RAM @ 100%. Attached. Tomorrow, I'll replace the MB and RAM while retaining the drives. I thought that I had a random webpage open to my server from one of my smart TVs, as the overload mostly happened at night, but today, it happened without anyone in my house. Please look at my diagnostic and let me know what I did wrong this time. I am 100% confident that the issue was caused by operator malfunction. Thank you again. Chas "JorgeB mentioned "You are also having OOM, in your case it was caused by dotnet, so see if you find can find the container that uses that." JorgeB I am not clear on the meaning of OOM?
November 27, 20241 yr Author Sorry, it dawned on me OOM = Out of Memory. I am unable to access the diagnostic that I uploaded in the other thread to move it here. I will have to wait ti the next partial freezeup

November 27, 20241 yr Author Thank you, I just updated emby, is there anything else that you might suggest other than removing the container?
November 27, 20241 yr Community Expert Are you doing things like RAM transcoding? If so switch it back to having transcodes on the cache drive.

To avoid running OOM, make sure any caches are mapped to a disk - for the high CPU usage, not much you can do if you don't use a GPU to offload the transcode
November 27, 20241 yr Author I am moving emby to my larger cache pool, to see if this helps. I will also bu upgrading my system on Friday new MB, CPU and ram. I'll see if that helps. Thanks Chas
November 27, 20241 yr Author Well, I stepped away and once again 100% CPU and 100% ram. I just pulled another Diagnostic, maybe this will give better information than I do. Thanks again for any assistance Chas tower-diagnostics-20241127-1318.zip

Emby is pulling down a large portion of the resources, but you also have a lot errors on one of your drives: Nov 27 11:39:03 Tower kernel: BTRFS info (device nvme1n1p1): read error corrected: ino 20006314 off 40960 (dev /dev/sdt1 sector 172007976) Nov 27 11:39:12 Tower kernel: BTRFS warning (device nvme1n1p1): csum failed root 5 ino 20006316 off 4096 csum 0x8941f998 expected csum 0xdedc4706 mirror 2 Edited November 27, 20241 yr by Michael_P
November 27, 20241 yr Community Expert To add - your EX900 nvme is about 400 TB over its rated endurance, might be time to replace it.
