Question

我正在使用maven jetty插件，版本9.1.2.v20140210。自从我24小时前启动服务器以来，有三次我在日志中遇到了这个例外：

每次都有三种不同的文件。请求日志中的相关条目似乎是

[04/Mar/2014:21:33:31 +0000] "GET /favicon.ico HTTP/1.1" 200 93062

据我所知，它对网站没有任何负面影响。

我甚至不知道从哪里开始诊断这个问题 - 任何帮助都表示赞赏。很高兴发布任何必要的内容。

Answer 1

也许客户端工作得太慢而无法正常创建HTTP连接，所以一段时间后，服务器会针对该特定请求抛出java.util.concurrent.TimeoutException。

你的情景可以吗？
