apache stop하면 http not running 이라네요~

[root@www bin]# ./apachectl start
./apachectl start: httpd started
[root@www bin]# ./apachectl restart
./apachectl restart: httpd not running, trying to start
./apachectl restart: httpd started

위에처럼 restart가 되지를 않아요..
재부팅하고 난 다음에도.. start가 안됩니다.. 80포트는 열려 있는데.. 안되네요~

[root@www bin]# ./apachectl configtest
Syntax OK
구문오류도 아니에요..
왜 저런 현상이 일어 나는지 이유를 알수가 없어요
일일이 httpd 데몬을 다 죽여도 안되구요.
뭐가 잘못 되었는지 이유를 알수없어요..
가르쳐 주세요

참고로요
root@www bin]# ps -ax |grep httpd

stop 하면 이런 메세지가 나와요 도대체 어떻게 되는건지..

error_log 가보면..

address already in use: make_socket: could not bind to port 80 이라고 나옵니다..

뭐가 문젠가요 ??

며칠째 이러고 있습니다  ㅠㅠ
