Python은 SWAP 파일의 거의 30%를 사용하며 점점 더 커지고 있습니다. 이게 괜찮을지 모르지만 스왑 파일이 40%를 넘으면 조직의 누군가가 알림을 설정해 놨는데 일시적이고 변경할 수 없는데 해당 서버에서 계속 알림이 와서 짜증납니다.
Bitbucket, PostgreSQL 및 Apache가 이 서버에 설치되어 있습니다. 시도해 보았지만 swapoff -av && swapon -av몇 시간 후에는 이전 크기로 돌아가고 계속해서 커졌습니다.
문제는 이 서버의 Python 프로세스가 무엇을 사용하고 있느냐는 것입니다. 물론 Bitbucket이나 PostgreSQL에서 사용하는 것은 아니지만, 외부 서버와 일종의 네트워크 통신을 하는 것 같으니(저희 회사의 Bitbucket도 외부 사이트에서 사용 가능) Bitbucket과 연동하여 사용할 수도 있을 것 같습니다.
이 프로세스는 무엇을 위한 것인가요? 어떻게든 제한할 수 있나요?
폴리스티렌
물론 SWAP을 확장할 수 있지만 호기심 때문에 그것이 무엇에 사용되는지 알아야 합니까?
