지난번에도 비슷한 내용으로 게시물을 남긴적이 있는데...

수동으로 전이중 설정을 하고 몇달간 잘 돌아가다가
오늘 아침에 다시 같은 현상이 발생했습니다.

수정 전이중 설정을 다시 자동협상으로 변경하니 살아났습니다.
그래서 다시 자동을 수동전이중으로 바꾸니 또 잘 돌아갑니다.

로그파일들을 쭉 보고 있는데 그냥... 갑자기 네트워크가 나간거 밖에는 알수가 없습니다.
도대체 원인이 무엇일까요

지금 생각해보면 서버가 거의 10년 가까이 되었고 (2013년산)
네트워크 포트가 오래되서 죽는게 아닌가..
예상을 해봅니다.

다행히 내부네트워크는 죽지않아 살릴수 있는게 

그나마 다행이라 생각됩니다.

흠....

로그를 올려봅니다.
