뭔가 아이디랑 비번을 대입해서 이런 식으로 계속 쌓이고 있습니다 -_-a?;;
해당 아이피를 막는 것이 해결방법인지 @_@;;
우선 nginx 에서 user.conf 파일에서
location / { ... proxy_read_timeout 150; ... }
이렇게 수정해주기도 했고요..

에러가 발생할 때 타임아웃을 늘리는 것은 해결책이 아닙니다. 증상을 숨기고 서버 상태를 더 나쁘게 만들 뿐이지요. 어떤 경우에도 1분 이상의 타임아웃 설정은 권장하지 않습니다. 특히 PHP에서 타임아웃이 발생할 때는 오히려 타임아웃을 더 줄이는 것이 도움이 되기도 합니다.
버퍼 크기가 부족하다는 오류는 버퍼 크기와 관련된 여러 가지 설정을 조정하는 것으로 어느 정도 제거가 가능하지만, 악의적인 방문자 때문에 발생하는 오류라면 그냥 오류가 나도록 내버려두는 편이 안전할 수도 있어요. 오류가 나지 않으면 해당 요청이 공격자의 의도대로 작동하여 정말로 해킹당하거나 스팸이 등록될지도 모르니까요.
이상한 요청을 보내는 IP는 차단해 버리세요.
