갑자기 에러로그가 쌓입니다.

윈도우서버에서 그누보드(아미나빌더)를 사용중입니다.

별다른 소스를 건들지 않은거 같은데요.

어느순간 아래와 같은 에러가 에러로그파일에 계속 쌓입니다.

사이트 이용에는 전혀 문제가 없는데

로그파일이 계속 쌓이다보니 계속 지워줘야되네요...

에러가 생기는 아이피들은 이상하게 봇 아이피가 대부분입니다.(구글봇,빙봇등)

head.sub.php

117 118 121 번째 줄을 보면

<script src="<?php echo NA_URL ?>/js/common.js?ver=<?php echo G5_JS_VER; ?>"></script>  
<script src="<?php echo G5_JS_URL ?>/wrest.js?ver=<?php echo G5_JS_VER; ?>"></script>
<script src="<?php echo NA_URL ?>/js/nariya.js?ver=<?php echo G5_JS_VER; ?>"></script>

이 라인인데요..

어디를 손봐야할까요??
