Linux oom is not working

[donjuanplatinum]

Hello everyone, I have a question. It seems that my system's OOM killer won't trigger,I have confirmed that the vm.panic_on_oom=0,vm.oom_kill_allocating_task=0.But when I ran a test software that continuously requested memory, OOM did not work and caused the system to freeze when the memory usage reached 98%

this is my version

it seems system enter the thrashing before invoke oom killer
you can check the section "What is thrashing?" and "What is the Out Of Memory (OOM) killer?" from the memory faq:
