Thanks, I'll do that and see if it goes away. Also, I now read up more (sorry!) and I can attach diagnostics next time.

I'm warnings about Hardware Check Events from Fix Common Problems plugin - mcelog is installed, details of the reported errors are below. What is going wrong? Errors in log look like this: Jul 26 00:13:23 Unraid kernel: CPU: 3 PID: 25549 Comm: kworker/3:1 Tainted: G O 5.10.28-Unraid #1 Jul 26 00:13:23 Unraid kernel: Call Trace: Jul 27 09:26:21 Unraid kernel: mce: [Hardware Error]: Machine check events logged Jul 27 09:26:21 Unraid kernel: [Hardware Error]: Corrected error, no action required.
