Hi all,
I'm a relatively new Unraid user and I'm having a few issues.
A couple of times a week I'm losing access to either my Docker Service or my User Shares. It's never at the same time, but either of them happening will mean I need to reboot my system. After a reboot everything comes back up as expected and then runs for a couple of days.
The errors generally occur when my partner is watching media on Jellyfin, but I've also had it pop up while writing files to the cache/array.

From what I've seen from other posts, segfaults are usually a CPU or RAM issue. With a young son I don't have heaps of spare time to troubleshoot, so I was just wondering whether there's a way that I can narrow down which bit of hardware is likely the issue, or if it's something else entirely?

Quite happy to run through the a memtest, but if it's a CPU or NVMe drive I currently don't have anything I can swap out so I'll have to deal with it for a wee bit longer.

Thanks in advance! Being able to save a bit of time by decoding the diagnostics would be a welcome help.

Also - please no judgement for the single drive pool with appdata etc on it - I'm saving for a second drive at the moment :)

Make sure this has been taken care of:

I was unaware of the RAM limitations - thanks for that @JorgeB!

I'll check my speeds next time I reboot and see how it performs moving forward.

Dropped my RAM speeds to the ones suggested in the linked article, and then finally had the need to push a bunch more files through to the server - under 1GB, but a lot of files (over 100,000). Unfortunately I've had the same issue where the User Shares disappeared during the transfer.

Didn't get the chance to download the diagnostics as I remote booted the system to allow others to keep using it.

Any other ideas from my initial post? Cheers

Please post new diags after this happens.

Finally had another dropout during daily use.

Diags attached this time since I was at home!

Btrfs is detecting data corruption on the pool, start by running memtest.

Finally got some time to test everything.
Ran memtest and got a heap of errors. Narrowed it down to a pair, and then a single stick of RAM (recently purchased I might add).
Just received warranty replacement RAM, have run memtest on it and it passed with no errors.
Haven't had the chance to properly test the server yet, but with such glaring failures in memtest I'm pretty confident that this is the root issue, so I'll mark it as a solution.

Note for newbies - run memtest first.

Thanks @JorgeB for holding my hand like I was a child haha.
