Unexpected EOF read on the socket

SCG基于Spring WebFlux，不应该出现mvc相关的异常栈：
org.springframework.http.converter.HttpMessageNotReadableException: I/O error while reading input message; nested exception is java.io.EOFException: Unexpected EOF read on the socket
at org.springframework.web.servlet.mvc.method.annotation.AbstractMessageConverterMethodArgumentResolver.readWithMessageConverters(AbstractMessageConverterMethodArgumentResolver.java:218)
确认一下这是SCG日志中的信息，还是后端服务返回的信息。
看一下后端服务的处理逻辑，这个错误可能是请求方发送的报文不全。
不一定，我这边换成Nginx就没这个问题了，验证出现的问题是request body丢失或者丢包，下游服务器接收的body长度小于Content-length，一直等待读取，但是具体原因还未查到
If this is still happening with Spring Boot 3.2 and Cloud 2023.0, please take the time to provide a complete, minimal, verifiable sample (something that we can unzip attached to this issue or git clone, build, and deploy) that reproduces the problem and we will reopen.
