November 20, 2025Nov 20 Hi thereUnraid (7.1.4) has been very stable for me for months, until the last couple of days. I upgraded to 7.2.0 and started getting instability, with the system hanging after 10-20 minutes. No WebGUI, no SSH, won't respond to a power button press to clean shutdown.I upgraded again to 7.2.1 - no change. I downgraded to 7.1.4 - no change. Same instability.I've added my diagnostics in the hope that someone can tell me what they think is happening.Thanks 😀Matt usul-diagnostics-20251120-2212.zip

Same instability.That suggests it's not the upgrade, and it may have developed a hardware problem, but enable the syslog server and post that after a rash, in case there's something there.
November 22, 2025Nov 22 Author Thanks @JorgeB . I found the grapics card had become unseated, so that could have caused some random fluctuations. That's been fixed. I ran memtest86 for 1.5 hours, with no issues shown; I'm going to run it for 4 hours today and see what happens.Unraid was up for 9 hours last night. Only when I accessed the WebGUI this morning did it crash. I've posted the syslog. It doesn't indicate any errors to me, apart from the php-fpm pool warning.Parity check completed during the uptime last night. syslog
November 22, 2025Nov 22 Community Expert Yep, nothing relevant logged, suggesting more a hardware issue.
November 22, 2025Nov 22 Author I'm new to Unraid troubleshooting. If a plugin or a docker caused the crash, would this show in the syslog?
November 22, 2025Nov 22 Community Expert Solution Not typically, but you can try is to boot the server in safe mode with all docker containers/VMs disabled, let it run as a basic NAS for a few days, if it still crashes it's likely a hardware problem, if it doesn't start turning on the other services one by one, including the individual docker containers.
November 28, 2025Nov 28 Author I tracked down the issue - it’s a CPU spike to 100% caused by a deprecated Docker container - Space Engineers - which left nothing for the Unraid OS. Keeping that container off has kept the system stable. The key for me was understanding that the kernel panicking before writing to the syslog (rsyslog on a RPi works well) indicated a hardware-caused lock up but not a hardware error. Although frustrating I’ve learned a lot more about how Unraid operates and how to troubleshoot it, so it’s been very useful.
