Not sure what it is about memtest86, but in my experience it doesn't find most memory errors. I've had serious memory issues, that trigger memlogd, dmesg, or similar about EDAC/ECC errors. I try memtest86 over night, no errors. Restart the node and get more errors. This seems to happen most of the time, only in the rare case can I reproduce errors I see in a production system with memtest86 reports.
