스왑 드라이브가 나열되었으나 사용되지 않음

메모리 집약적인 프로세스를 수행해야 하기 때문에 16GB USB 썸스틱을 스왑 드라이브로 사용하고 있습니다. 스왑 드라이브가 목록에 표시되고 마운트되었지만 ODROID가 2GB에 도달하면 메모리 부족으로 인해 정지됩니다. 이것은 정보입니다.

그러나 활성 프로세스가 실행 중일 때는 스왑이 작동하지 않습니다. 사용해보면 free -mRAM이 완전히 소진되고 스왑 영역이 여전히 0으로 표시되는 것을 볼 수 있습니다.

master@odroidxu4:~$ free -m

현재 ODROID는 메모리 부족으로 인해 정지 및 종료됩니다.

이 문제를 해결하는 방법에 대한 아이디어가 있습니까?

이제 mkswap도 사용해 보세요...

실제로 마지막 mkswap은 내 swapon -s를
