안녕하세요
 리눅스에 아파치 서버를 사용중입니다.
 아파치 데몬 프로세스가 핸드링이 안되여
 killall httpd
kill -9 pid
apachectl stop
 해도 프로 세스가 죽지를 않는군요
 그래서 reboot 명령을 때리면 각 테미날(네텀)에 브로드 케스팅만 날리고 실제로는 reboot이 
안됨니다.  다른 명령어들은 다 standard in 으로(키보드)로 치면 stnadard out(모니터)로 결과가 
리턴되는데  process와 관련된 명령어들(top,ps,kill killall)등은 무반응입니다.
  전원을 완전이 날렸다가 올려서
그래서 /var/log/message 파일을 보면

 물론 httpd kill fault 가 나있습니다.
----------------------------------------------------------------------------------------
  와 같이 되어있습니다.
 하드를 교체 해 주어야 되나여...
 서버를 1년6개월정도 아무 이상이 없었는데 1주일새에 2번 정도 발생했습니다..
 httpd process만이 이상하게 돌아가는데 프로그램 수정된것도 없구 그사이에 rpm이나 package ins
tall 한것도 없습니다.  해결 방안을 알고 계신분들 부탁좀 드리겠습니다
 혹기 bad sector 난것 알수 있는 명령어나 유티리티가 있다면 소개줌 부탁드립니다.
  읽어 주셔서 감사합니다.
