500 Internal Server Error 채택완료

1. vps로 서버이전 중입니다.

2. 도메인 땡겨오느라 불안정한 상황입니다.

어제까지만 해도 불안정하긴 했으나 구서버나, 신서버나 접속이 되긴 됐었습니다.

그런데 오늘부터 갑자기 엄청나게 딜레이 생기더니 500에러를 뱉어내네요;; (그 사이 손댄것은 없습니다.)

3. 티켓을 이용하여 apm등을 설치했는데, 보니까 아파치랑 nginx랑 두 가지가 깔려있었습니다.

우선 아파치부터 에러코드를 살펴봤는데요

라고 떠있고 nginx 에러로그같은 경우에는

라고 뜹니다. 클플 사용중이며 ssl도 아마 적용되어 있는걸로 압니다.

접속이 잘 되다가 갑자기 이러는 이유를 모르겠습니다. 

무엇을 보면 되는걸까요?
