Jetty中的頻繁超時異常

Question

我正在使用maven碼頭插件9.1.2.v20140210版本。自從我開始服務器三次24小時之前我在日誌中獲得這樣的例外：

2014-03-04 16:34:01.878:WARN:oejs.HttpChannel:qtp1119397307-111: Commit failed java.util.concurrent.TimeoutException: Idle timeout expired: 30001/30000 ms

它一直是每次三個不同的文件。請求日誌中的相關條目似乎是

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

據我所知，它對網站沒有不利影響。

我什至不知道從哪裏開始診斷這個問題 - 任何幫助表示讚賞。很高興發佈任何必要的。

也許客戶端工作得太慢以至於無法正確創建HTTP連接，所以過了一段時間，您的服務器將針對該特定請求拋出java.util.concurrent.TimeoutException。

在你的情況下可能嗎？
