Unexplained, one-time NVMe pool "error resulting in data corruption"

Five different users on these forums resulting in failed memtest runs within two months of each other, which helped to steer them into fixing the issue that should have been “evident”… without them actually running the tests? [1] [2] [3] [4] [5] [6]

It takes very little time and effort to run a memtest to rule out bad RAM for a NAS server that writes and reads important data. It’s not the end of the world to run them. I even do so for my main and backup servers when I have to power them down or do an upgrade. Since I’ve already powered down, I might as well run a couple passes, in the same spirit as running extended SMART tests on my drives.
