I have 'Kernel stack memory corruption detected'

• I hade a ' Kernel stack memory corruption detected ' restart problem in the past. Mac OS version: 21E230

I have an external boot for my iMac 18.2 (2017 21inch 4K - 1TB Fusion drive) - system. Using the internal drive works in Monterey, but below my expectations.

I had kernel paics before. Previously I thought it was my Thunderbolt3 device + WD Black SN750.

To solve the crashes, I have used the internal drive for some time again, but it is slow.

So I went back to the Thunderbolt. The crashes came back. I switched Thunderbolt drives. It is still there. It is not the drive.

QUESTION:

The external boot is on a WD Black SN850 500TB SSD, PCIe-4 - while the Thunderbolt drive is PCIe-3• . The information given was that the WD PCIe-4 would be backwards compatible.

Can running a PCI-4 card on a PCI-3 drive be the cause• for the kernel panics? Just a glitch every now and then; only when the system is sleeping?

Is it harmful• l for the system to repeatedly restart after a kernel panic? (once in a while, say 48 hours, and only when the system is asleep); I do not leave documents open; sometimes Lightroom (LR or LRc).

• I also have a 1Tb PCIe-3 card that is slower than the WD (reading 1.700 Mb versus a faster 2.400 Mb measured in the same Thunderbolt3 drive). So little prformance to sacrifice. Startup will be 50 secs against 35 secs. Just do it?

Kernel Panics are predominately caused by hardware faults or faulty third-party kernel extensions.

How about posting the kernel panic

...preferable three separate reports in three separate "Additional Text" box for ease of reading and comparison, and see if there is an establish a trend .(see menu below.)
