我们有一个Akka HTTP服务器为AWS上的一些scala JS内容提供服务。我们注意到一段时间后，服务器开始在日志中抛出下面的错误，尽管如此，某些URL的工作却在浏览器中出现Failed to load resource: net::ERR_CONTENT_LENGTH_MISMATCH错误，但某些文件无法正确下载。服务器日志看起来像下面（它正是在所有情况下相同的错误）：Akka Http错误：InvalidContentLengthException

我们正在运行阿卡版本2.4.7和OpenJDK的版本，如果我们重启阿卡1.8.0_101-b13.The错误消失HTTP服务器，但几个小时后又回来了。
不知道是什么导致了问题。任何帮助将不胜感激。
