at java.lang.Thread.run(Thread.java:619)以上是异常信息，应用场景如下：在一个jsp页面使用的
<jsp:include page="handMsgButton.jsp"/>
这个报错信息，并不是一直都有，别说什么目录不存在，文件不存在的话，文件肯定是存在的，是偶尔报这个错，报了之后就会一直报，直到重启才会OK，windows环境，有的说缓存，有的说系统打开文件过多导致，不知道有哪位朋友有遇到同样问题，或者有所了解，有什么方案，解决办法找到问题根源，可以彻底解决此类问题，JSP异常

Answer 1

用<%@ include file=感觉比较靠谱，猜想可能是session之类的到期了，你页面需要的数据引用不到引起的吧。要重新加载。

Answer 2

不过那个缓存 flush="true" 确实可以试下是不是这个原因，但是还是未分析出问题根源

Answer 3

只是依据目前的信息很难定位错误啊。能看一下handMsgButton.jsp么？
