apache 관련 질문입니다.

리눅스 서버에 Apache/2.0.49 를 작년부터 설치해서 별 문제 없이 사용하고 있었고,

얼마전까지만 해도 별 문제가 없었습니다.

그런데 갑자기 1달쯤 전부터 서버가 죽기 시작하더니, 주 1회 다운되던 서버가 급기야 일 1회 다운되는 상황입니다.

로그를 봐도 정확히 모르겠고,

top 를 해 보면

위와같이 httpd 가 엄청나게 많이 떠서 메모리를 엄청나게 잡아먹고 있습니다.

ps -ef 를 하면 말도 못할정도로 프로세스가 떠있지요-_-

최근들어 갑자기 접속자가 늘어났거나, 특정 서비스를 추가 한적도 없습니다.

하도 답답해서 오늘 서버 메모리를 1G 추가 했는데 불안불안 하네요.

httpd 가 클라이언트가 늘어날때마다 하나씩 늘어나는건 아닐텐데,

혹시 이런 비슷한 문제를 해결 해 보신분 있으면 해결책좀 알려주십시요.
