톰캣 - jsp - mysql 서버 운영중인데 도움을 부탁드립니다 ㅠ
안녕하세요.
저는 지방대 컴퓨터과 연구실에 다니는 학부생입니다.
지금은 안계신 선배님이 톰캣 - mysql 이용해서 교수님 홈페이지를 만드셨는데
잘돌아가다가 최근들어 매일 서버가 죽네요 ㅠㅠ
(증상은 다른 컴퓨터에서 홈페이지에 접속이 안되고
서버 컴퓨터도 인터넷이 안되네요. )
에러 로그인데요. 이 에러가 매번 납니다.
//localhost.2010-05-20.log
2010. 5. 20 오후 9:24:54 org.apache.catalina.core.StandardHostValve status
경고: Exception Processing ErrorPage[errorCode=404, location=/jsp/errors/404_error.jsp]
ClientAbortException: java.net.SocketException: No buffer space available - exhausted attempts to queue buffer
버퍼에 소켓을 더 이상 만들수 없다는 것 같은데 그 이유를 도저히 모르겠습니다.
혹시 이런 에러를 경험해보셨거나 아시는 분 답변을 간절히 기다릴게요 ㅠㅠ 도와주세요,,
전체로그입니다..

보통 제대로 셋팅
보통 제대로 셋팅 안된채로 오랫동안 방치된 서버가 급작스레 죽는경우..... 웹서버 로그 데이터가 무식하게 커져서 그런경우가 종종 생기더군요..
