APM환경의 server를 구축하고 관리하고 있는 사람입니다.
래드햇 리눅스 페토라 2를 사용하고 있는데요.
부팅한 후 시간이 조금 지나면 cpu 가 100%가 됩니다.
원인을 찾을 수가 없네요.
다음은 top명령어의 결과입니다.

웬만하면 혼자 해보려고 QnA 뒤지고 책을 보지만 도저히 알아낼 방법이 없군요.
아직도 왜 cpu가 100%를 차지하는지 원인을 알 수 없습니다. ㅜㅜ
혹시 누가 대량의 ping을 날리는지.. 해킹을 당하는건지.. 걱정이 되어 이곳에 올립니다.
고수님들의 답변 부탁드립니다.

웬만하면 혼자 해보려고 QnA 뒤지고 책을 보지만 도저히 알아낼 방법이 없군요.

고수님들의 답변 부탁드립니다.
