웹서비스 통신시 아래와 이러한 오류가 발생합니다.

100건의 1건정도발생하는 오류입니다.
일단 데이타가 파싱되어서 넘어오면 문제가 없는데 was 쪽에서 이렇게 오류가 떨어져서 손을 쓸 수가 없네요.

서버는 aix 5.3에, jdk 1.6, 웹로직 10.3 을 사용하고 있습니다.

클라이언트 모듈에서 allowChunking =false 이런것도 해보고, mtom 기능도 빼보고 했는데 동일하네요.

와 같이 나오고,
클라이언트에는
javax.xml.ws.WebServiceException: org.apache.cxf.binding.soap.SoapFault: Error reading XMLStreamReader.

이렇게 나옵니다.

이놈만 해결되면 웹서비스 문제는 없을 거 같네요.

매번 답변에 감사드립니다.
