When I execute the following command to load the memory, there will be a situation where it gets stuck until the program releases the memory (the real situation is when running a Java process and the system freezes, requiring a hard restart)
I discovered this issue on a 32GB test server and created a new test virtual machine for testing
For example, I have a server with 1GB of memory
stress-ng --vm 1 --vm-bytes 680M --timeout 10s --metrics
