안녕하세요. ubuntu서버를 운영한지 3달된 SP입니다.
android 빌드를 하는 ubuntu서버가 가끔 이유 없이 죽는데
이 때마다 정확한 원인을 파악하기가 힘듭니다.
unix나 windows처럼 guarantee되는 OS가 아니다보니 물어볼데도 없구요…
message파일에 뭔가 남긴 하는데 원인이 무엇인지도 찾기도 힘들고
google조회 만으로는 한계가 있네요…
이럴때 고수님들은 어떻게 하시는지 궁금합니다.
참조할만한 site나 좋은 책 있으면 답장 부탁드려요~
아래는 이번에 생긴 로그인데…원인이 무엇인지 파악하기 힘드네요…ㅠㅠ

단순 빌드는 아닌거 같은데.
android가 커널 관련해서 뭔가 만지작 하나요? =.=
only user level 이라면 os 를 죽일리는 없을텐데요…

아니요… 그냥 application compile하는 서버에요.
커널은 건들지도 않습니다.

자바관련 또는 자바 포함 대형 프로그램 컴파일 하면
우분투 시스템이 맛이 가는 경우를 경험 했습니다.
CPU 사용률이 100% 가까이 지속되며
다른 GTK 어플 컴파일과 달리 뻣거나 뻣는 상태가 지속되는걸 경험 했으니 참고 바랍니다.
컴파일 시 htop 등으로 살펴 보시기 바랍니다.
