AsyncHttpClient 上传两个以上文件出错 急！

============问题描述============

AsyncHttpClient上传两个以上文件到服务端，服务端接收的时候报错
服务端是用Java的 struts2框架写的，tomcat服务器，tomcat设置如下：
  <Connector port="8080" protocol="HTTP/1.1" 
               connectionTimeout="100000" 
               redirectPort="8443" URIEncoding="UTF-8" 
   maxHttpHeaderSize="8192"
               maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
               enableLookups="false" acceptCount="100"
               disableUploadTimeout="false" />
我开始以为是客户端上传文件大小出错，所以每次上传两张图片很正常，三张就报错
但是后来我实验了上传一个10多M的文件加一个图片，很正常，但是再增加一张图片就报错。
搞了好久，快疯掉了，各位大侠救命，解决问题马上给分，不胜感激！！！
每次报错信息都是如下：

============解决方案1============

从提示信息“Stream ended unexpectedly”来看，可能是你的android程序没有把数据传完就断开连接了。

============解决方案2============

是怎么添加附件的，是不是上传的格式编码问题，你试下两张能压缩上传么？
