java - EOF/函数参数无效(错误号 :4022) with Jetty 9

Question

无法找到是否有静态内容的配置。它没有下载js文件，我希望它是因为与其他文件相比，它的大小更大。

Jetty 版本:9.2.10
操作系统:惠普不间断

我可以在jetty debug中看到以下错误

Answer 1

您的意思是 Jetty 正在上传或发送内容，而不是下载。从你的堆栈跟踪中可以明显看出这一点。

您遇到的主要问题是，当尝试刷新连接时，连接会因 EOF 而终止。

但是，您遇到的更根本的问题 java.io.IOException: Invalid function argument (errno:4022) 并不是 Jetty 可以修复或解决的问题。这是操作系统级别的错误，表明无法使用文件描述符进行网络连接，或者文件系统错误，表明无法使用文件描述符访问磁盘上的文件。

无论哪种方式，您都应该检查操作系统、文件系统、WAR 文件的运行状况、文件系统临时目录，并考虑升级 Java JVM ( 1.7.0_25 expired back in Nov 15, 2013 )
