Clear Linux hanged when running heavy resource job

I installed Docker on Clear Linux and ran a container that requires more than 100% of the resources (CPU, Memory)

Typically, even when these containers are running, the Linux system is not deadlocked. (Although I don’t know the reason.)

However, Clear Linux has come to a deadlock in all its functions. This made neither Terminal nor SSH work.

I tested it countless times, but the results were the same.

Where does this difference come from?
