MP 1,1-5,1 WHEA Error 18 Under W11 Mac Pro 5,1 During File Transfer to Storage Pool

[andysa1966]

For what ever reasons I am managing my music library and syncing to iPod via iTunes under W11 (Open Core). My C Drive is 1TB NVME on PCIE. Its a large library, over 400GB, I back it up to a sata 1TB drive under the optical drive and for extra protection I have 4 x SATA 2TB HDD pooled to create a single 2TB mirrored second back up drive.

During back up the system is crashing reporting a WHEA fatal hardware error code 18, this is repeatable. If I pause backup every few minutes I can complete the back up.

Its a single 3.46 cpu tray, I've swapped out the CPU and ram, still the crash persists, all temperatures are ok.

Am I asking to much of the CMP hardware backing up this much data to 4x HHD

this way?

Error traps sometimes give codes that are misleading. In this case, the transfer timeout got blamed on the CPU. But it's more likely a drive filling up cache, and stalling while it flushes cache to disk (or to main TLC or QLC storage).

Is this happening while copying to the SSD in the optical space? If so, that SSD may be a cheepo QLC model, or even a cheap TLC with limited cache.

Or is it happening while copying to the 4x HDDs in the main bays? If so, one drive is lagging, and probably failing.

In either case, when you pause every few minutes, it give the slow drive enough time to catch up.
