我在wildfly 10上运行ejb项目并遇到此错误消息，

UT000128: Remote peer closed connection before all data could be read

以上信息是否值得关注？

网上没有太多信息。这些是一些参考：

下面是堆栈跟踪，

关于 / {app} / block / send-receive-updates 或 / {app} / block / receive-updated-views ，这些是ICEfaces组件中的心跳监视机制，用于维护Web服务器和客户端浏览器之间的连接。

根据我的理解来源：

答案 0 :(得分：1)

当您的服务器丢失与客户端的套接字连接时，可能会发生此错误，主要原因是超时或强行关闭任一端的连接。

答案 1 :(得分：0)

我得到了相同的错误代码（UT000128），而我的应用程序想要在执行某些重试机制后读取请求主体。它将消耗有效载荷，以便我无法再次读取它们，Untertow返回UT000128。

我的解决方案是使用包装器在重试机制中复制请求主体。如果您遇到同样的情况，我希望这会有所帮助。
