오늘 아침부터 낮까지 5분간격으로 uptime 저장한 로그입니다.

요즘 자주 ping 은 되나,내부 서비스가 다 중단되어 접속불가등의 상황이 생기더군요.

재부팅 밖에 해결방법이 없어서 파악할려구 이와 같은 로그를 저장해본건데여

(서버 다운 당시의 로그도 저장 안됨)

08:35:05 <- 요 시간대에 load average: 28.73, 15.71, 6.85 이렇게나 높아졋네요.

이 서버가 현재 메일 서버 인데,  스팸일까요.. 아님 해킹을 의심해야할까요?

오픈 릴레이등은 닫혓으나 프로세스를 보면

처럼 qmail-remote 에 알수없는 메일이 넘 마니 가네요.

원인을 더 파악하기위한 방법이 뭐가 있을까요?
