Hello everyone,

Out of ideas so reaching out for some help... For the past few months (not sure how many exactly but more than 4 and less than 7) I have been having an issue with my unRAID server: it shuts down (at what appears to be) randomly by it's own.

Hardware: My server is an CWWK Q670 motherboard with an i5-14500 cooled by a Noctua NH-D9L, 32GB RAM, a couple NVMe, and as PSU a Corsair SF850L. All inside a properly cooled Jonsbo N3.

Software: I have been running 6.12.15 for months now and started to think maybe an update would solve this weird problem, a few days ago I updated to 7.1.2, nothing changed, same problem.

My server is at my parents home, which is a flight away from mines, so not easly accessible, however with the use of tailscale it's basically a no problem. Also, on the BIOS settings, I have it set up so it always powers on when it detects power on the wall. So, this way, when the server powers off alone randomly, after 5 minutes or so it is powered back on like nothing happened (except it started a parity check). The way I started noticing this was with the use of uptime-kuma I have on a VPS monitoring some of my services and alerting me that they are down and then back up again after said time.

As you see it's not that much of a problem thanks to that BIOS setting, but it's starting to bother me and especially worrying if it could scale to something worse (actually losing data, etc.)

So, I have no VMs, I do have a lot of dockers, and some SMBs. All the components are brand new and no more than 8 months old so still in warranty (except hard drives). I had a hard time getting the logs, since by the time I realized something bad happened the system was rebooted and lost all log data since it's stored in RAM. I saw in this forum you could enable Syslog Server to an array share, I did that. The system is rebooting at least once a week. Last time was this morning, the time before that was 2 and a half days ago.

Also, I had a smart plug lying arround and decided to use it on my server to monitor power outages. All correct, so I guess the problem is my server itself.

For reference, the last unexpected shutdown was around 2025-06-23 07:13:56 UTC+2 Time (This is when I received a warning so maybe a little bit earlier). I also happened at 2025-06-18 16:07:17 and 2025-06-15 20:44:26. I think all of this is in the log.

I am aware all this is most probably hardware related by what I have read, and that I should run memtest and try another PSU, the PSU I won't be able to do so until I go to my parent's on August, but the memtest is it ok to do it from home? Or should I be there?

I would attach the diagnostics file too, but unraid is not creating anything, the last one I have is from months ago (at least I can't find anything).

I don't know what else to say, thanks to anyone that reads me. :)

Server restarting by itself is almost always a hardware issue, or some issue with the power, if you have multiple sticks try using the server with just one, if the same try with a different one, that will basically rule out bad RAM.

Will do once I get to my parents in August, until then is there anything else I could do? Or would be a lost of time?

You can run memtest, but it's only definitive if it finds an error.

I am getting the same issues at the moment, every so often my array stops, server doesn't lose power or shutdown, the array is just stopped and there is nothing obvious in the system logs

Since this thread is not resolved, please start your own and post the diagnostics.
