为什么我在Linux上的Web服务中获得SocketTimeoutException但在Windows上却没有？

Question

我有一个如下的网络服务：

    @WebServiceProvider
    @BindingType(HTTPBinding.HTTP_BINDING)
    @ServiceMode(value = Service.Mode.MESSAGE)
    public class Service implements Provider<DataSource> {

    @Resource
protected WebServiceContext m_wsContext;
@Override
public DataSource invoke(final DataSource dataSource) throws WebServiceException {
    final MessageContext messageContext = m_wsContext.getMessageContext();
    final String method = (String) messageContext.get(MessageContext.HTTP_REQUEST_METHOD);
    if (method.equals("POST"))
        return invokePostMethod(dataSource, messageContext);
    throw new HTTPException(404);
}

private DataSource invokePostMethod(final DataSource dataSource, final MessageContext messageContext) {

    return new DataSource()  {

        @Override
        public InputStream getInputStream() {
            try {
                InputStream in = dataSource.getInputStream();
                System.out.println("Got input stream from client....Available bytes: " + in.available());


                in.close();

            } catch (IOException e) {
                                    return null;
            }
            return null;
        }

        @Override
        public OutputStream getOutputStream() {
            return null;
        }
        @Override
        public String getContentType() {
            return "text/plain";
        }
        @Override
        public String getName() {
            return "";
        }
    };
}
   }

现在我在Red Hat linux和Win7上执行这个Web服务。 在Windows上没有问题，但Linux的行为完全不同！ 客户端不断地从2-4个线程调用此Web服务。 一段时间后它返回“从客户端获得输入流....可用字节：0”（日志消息），过了一会儿我得到一个例外：
