apache 데몬이 많이 뜹니다.

아직 초보 서버 엔지니어 입니다.

며칠전부터 apache 에 자꾸 문제가 생긴것 같습니다.

[root@test bin]# ps -ef|grep apache

root     18994 18865  0 02:48 pts/0    00:00:00 grep apache

보통 이렇게 떠야지 정상인데..얼마전부터

이렇게 수십개의 apache 데몬이 뜨는걸로 나옵니다. 무슨 문제인지..

./apachectl restart 로 다시 시작하면 제데루 됩니다. (어쩌다가는 kill 로 해야지만 됨)
서버는 올해 1월달 이후로 한번도 그런적 없었는데..요즘 자주 그런현상이 나타나는군요..
혹시 무슨 문제인지요..? 고수님의 답변좀 부탁드리겠습니다.

참고로 현재 홈페이지는 11개정도 돌리고 있으며 트레픽은 거의 없는 상태 입니다.
