하나의 웹 서버에 2개의 랜카드가 장착되어 있어서 A ip로도 접속이 가능하고 B ip로도 접속이 가능한 환경입니다.
웹 소스 및 WAS는 A ip의 서버에 구성되어 있습니다.

A ip에서 조회되는 데이터랑 B ip에서 조회되는 데이터랑 같아야 정상인데
A ip에서는 조회된 데이터가 없습니다. 라고 표시되고
(똑같은 조건에서) B ip에서는 데이터가 조회 됩니다.
이러한 현상도 똑같이 조회 되는 화면이 있고 그렇지 않은 화면도 있습니다.

간간이 아래와 같은 에러 로그가 발생 하는데요..
flush하는 과정에서 문제가 있지 않을까 생각되는데..

급한 문제이니 빠른 답변 부탁 합니다.

* 환경 : 웹로직 9, java 1.5, beaver framework
