- Urgent
My Unraid server frequently becomes unresponsive, with the hardware fans continuing to run loudly even though access to the Unraid WebUI and Docker services is lost. Additionally, active SSH connections are disrupted, preventing any further login attempts. I have redirected the Unraid syslog to the array appdata, yet each time, I fail to identify any significant information within.
On this occasion, the server became unresponsive at 5:57 AM, and I proceeded to reboot it at 8:50 AM:

I'm experiencing an issue once or twice daily, How can I further investigate this issue? Could it be related to the SSD cache overheating, or is there another potential cause?
I have also made the notification files permanent, and I observed that there were no heating warnings around 5 AM.
