처음에는 여러 프로세스를 생성하고 종료하여 lxml 메모리 누수를 방지하려고 시도했지만 실패했습니다.
그래서 새로운 아이디어를 시도하기 전에 서비스 파일에 를 설정했습니다 OOMPolicy=stop.MemoryMax=2G
내 의도는 Podman 통계의 메모리 사용량이 2G에 도달하면 systemd의 OOM-killer가 (커널에서 SIGKILL 대신) 중지를 보내는 것입니다. 그래서 다시 시작됩니다.
그러나 메모리 사용량 podman stats은 164.9MB이지만 systemctl status결과는 입니다 Memory: 756.0K (high: 1.8G max: 2.0G available: 1.8G). (높은 부분은 무시하셔도 됩니다. 방금 시도해봤습니다 --runtime.)
물론 실험을 통해 뭔가를 보여줄 수 있겠지만, 메모리에 대한 설명을 듣고 싶습니다. 유닉스에는 제가 아직 이해하지 못하는 동작에 대한 이유가 있을 것이기 때문입니다.
