my system restarts automatically whenever I start training

[xxxgcat]

Hello, I'm using task06 Lung in MSD2018 for training, and my GPU is two nvidia3090.
I don't know why, my system restarts automatically whenever I start training.
Do you know the reason for this?
Is it because of insufficient GPU memory?
Or is it due to the size of the image being too large?

I guess it is the hardware issues you may be facing, check whether the power or the protection setting of your hardware are enabled, generally related to the power of your device
