I just bought a brand-new 2018 Mac mini (i5, 32GB RAM, 256GB SSD) and it has started Kernel Panicking (I assume? it stops outputting to the display and the fan gets really loud for a second, the LED stays on and I have to hold it for 10 seconds to restart it). This pretty much just happens under load, which is a real shame because I need to use it under load.
I would attach the crash log, but it appears that it's too long for StackOverflow.
