I've noticed lately in the last few months that my unraid keeps going down, where it is not accessible at all, the monitor connected to it is blank, not accessible via network, tailscale also says its offline...however when I go check the chasis, the pc is still powered on, so is the motherboard and gpu but the drives are spun down and no hdd activity. Whenever I power it off and on again, the parity-check shows that there are not drive errors. The hardware is far beyond what it is used for (mostly multi-media by 1-2 people at a time), and it doesn't crash under load but usually when I don't seem to be actively acessing it.
The frequency is not consistent either....sometimes it'll go 20-30 days without issue and sometimes it will crash in 2 days. I'm not sure where to check what could be going wrong. They syslog doesn't seem to show anything up with it. I have included the diagnostics file.
Please let me know if someone is able to troubleshoot this with me, or point me in the right direction or have experienced something similar.
