저희 서버중에 메일 관련 질문 드립니다.

안녕하세요. 저희 서버중에 갑자기 센드 메일만 돌리면 서버가 과부하가 걸려서 다른 서비스도 함께 죽어 버립니다. 그래서 누가 스팸 메일을 돌리나 싶어서 relay허용 여부를 알아봤으나 그것의 문제는 아닌듯 싶습니다. 서버 과부하로 인해서 TOP 명령어도 먹히지 않는 상황입니다.///

밑에 내용은 ps -ef 를 했을 때 나타나는 상황인데 이 내용이 무엇인지 알고 싶습니다.

이 내용이 이것의 5배정도는 나옵니다.

으 상황이 서버의 메일서버는 죽여 놓은 상태입니다. 제발 고수님들 부탁합니다.
