The faults seem to happen intermittently. Eventfully the dockers and VM disconnect. I had issues with my cache drive recently and removed it, so everything is running on the array currently.  The issue occurred prior to removing the cache drive also.

Have you run Memtest from the boot menu at least a pass or two?  (If you're booting via UEFI, you will need to temporarily switch to legacy for Memtest to work)

Thank you for the quick reply. One of the four DIMMs failed the test.
