我正在Glassfish 4服务器上用Java EE 6和Primefaces制作一个Web应用程序。我越来越频繁地犯同样令人讨厌的错误。我试过用谷歌搜索这个问题，但还没有找到一个有效的解决方案。有时，应用程序的执行完全没有问题，但突然间，同样的错误一次又一次地发生。这是我的堆栈跟踪：

同样的错误会发生好几次，但无法提供资源，如：jquery/jquery-plugins.js、layout/layout.js、jquery/j query.js、primefaces.js。所有这些都来自primefaces库。
这个错误已经困扰我很长一段时间了，我们将不胜感激！
这很可能是grizzly框架的一个错误。
可能导致错误：https://java.net/jira/browse/GLASSFISH-20681?page=com.atlassian.jira.plugin.system.issuetabpanels:all-选项卡
在那个Jira中，有一个jar补丁。复制到modules目录，清除OSGI缓存（删除glassfish4\glassfish\domain1\OSGI缓存），然后重新启动。这对我有效。
另请参阅：当返回（请求）多个大型响应时，Servlet中引发GF4错误超时异常
请注意，客户端以HTTP GET请求的形式从服务器获取资源。这意味着，对于每个CSS、JS或HTML文件，都会得到一个HTTP请求。
打开浏览器web控制台并单击网络。然后去任何一个网站，你会看到你收到了多少请求。
以下是关于你的问题的一些建议。
- 请尝试增加服务器的最大池大小。在此处阅读http://docs.oracle.com/cd/E26576_01/doc.312/e24936/tuning-glassfish.htm#abeea->调整EJB池设置
- 试着分析你的网络应用程序，看看是否有太多对同一资源的请求。如上所述，您可以在浏览器中执行此操作
- 分析JSP中无用的导入、包含或iFrame
我希望这能帮助
