내용으로 보아 커널 해킹인것 같은데...어떻게 해결을 해야할지를 모르겠네요.

위와 같은 내용이 출력이 되어
yum 으로 커널 및 기타 패키지를 업데이트 한후 리부팅하지 않고 다시 실행을 하였습니다.
위의 내용은 나오지 않지만
warning, got duplicate tcp line.
내용은 계속 많이 출력이 되네요.

아직 리부팅 작업은 못하고 있습니다. 혹시나 부팅이 되지 않을까봐요..

그리고 추가적으로 궁금한 점은 아래 내용입니다.
설치후 바로 체킹을 해봐도 아래와 같이 perl 관련 내용이 출력이 되는데..
정상적인 결과 인지..아니면 어떠한 조치를 해야 되는 내용인지가 궁금합니다.
