스왑 파티션이 채워질 때까지 10 분을 기다리거나 OOM 리퍼 + 충돌을 시작하기 위해 5 분 동안 기다리지 않고 OOM 리퍼가 원하는 것을 빨리 죽이는 것을 선호하기 때문에 디스크에 스왑 파티션이 없습니다 . 기본적으로 내 문제는 다음과 같습니다.
- 발사
eat_all_my_memory
; - 응답하지 않는 시스템으로 10 분 동안 기다립니다 (HDD LED가 항상 켜져 있음).
- 그 동안 TTY로 전환하십시오.
- 실제로 전환하려면 몇 분 정도 기다리십시오.
- 사용자 이름과 비밀번호를 입력하십시오.
- 몇 분 기다리십시오.
- 로그인;
- OOM 사신 때문에 로그 오프하십시오.
- 작동 할 때까지 5부터 반복하십시오.
- 사용
top
하고kworker
"작동"을 참조하십시오 ; - 다시 죽이다;
- 사신으로부터
eat_all_my_memory
죽었다 는 메시지를 받는다 . - 메모리가 해제되었습니다.
지난 12 분이 걸렸습니다. TTY에 로그인하려는 시도는 전체주기 시간에 영향을 미치지 않는 것 같습니다. 그때 몇 가지 질문이 있습니다.
- 시스템이 디스크에 아무 것도 쓰지 않는 이유는 무엇입니까? 스왑이 없습니다 !!!
- 어디에 쓰나요?
- OOM 킬러에게 최소 시간에 가장 큰 사용자 프로세스 또는 대부분의 메모리를 소비하는 프로세스를 종료하도록 지시 할 방법이 없습니다. 그때까지 OOM 킬러가 디스크로 아무것도하지 않고 작업을 수행 할 수있는 방법이 있습니까?
데비안, 우분투 및 이제 아치 리눅스에 문제가있어서 배포판과 관련이없는 것 같습니다.
편집 : 로그 파일 발췌
나는 15:28 쯤에 불쾌한 명령을 내렸다. 시스템에 남은 것이 없다는 것을 알기 전에 실제로 많은 시간이 걸리는 것 같습니다.
