무엇내 디스크 공간을 차지하고 있어서 정말 짜증이 납니다. 오늘 아침에 나는 "남은 공간 없음" 알림을 듣고 일어났고 몇 주 동안 내 디스크 공간을 잡아먹고 있던 것이 내 토렌트 파일이 아니라는 것을 깨달았습니다. du파일 시스템을 확인한 결과 다음과 같은 내용을 발견했습니다 .

( kern.log.1, syslog그리고 kern.log비슷한 줄이 있습니다)
매 시간마다 깨어나서 4개의 다른 파일에 120만 줄의 소름끼치는 대사를 외치는 이 괴물을 어떻게 죽일 수 있습니까?
아니면 더 심각한 문제로, 이 줄을 기록하는 것이 무엇인지 어떻게 확인하고, 이를 중지하며, 어떤 로그를 안전하게 삭제할 수 있습니까?
편집 1: 답변해주셔서 감사합니다. 저는 Linux/Unix에 무서운 생물이 없다는 것을 알고 있습니다. :D 저는 운영 체제의 새로운 풀타임 사용자이고 지금까지 모든 것이 (대부분) 잘 작동했기 때문에 약간 당황스럽습니다.
어쨌든 출력은 다음과 같습니다 lspci.

문제는 01.1, 01.3, 03.1은 PCIe GPP Bridge, 07.1, 08.1은 이라는 것 입니다 Internal PCIe GPP Bridge 0 to Bus B. 하지만 이들이 어떻게 다른지, 왜 다른 것들은 오류가 발생하지 않는지 잘 모르겠습니다. 이것을 더 디버깅할 수 있는 방법이 있나요?
