Tomcat抛出异常:ClientAbortException: java.net.SocketException: Connection

在做一个小网站的时候,写了一个通过servlet实现文件下载功能的页面。当我点击超级练级,弹出下载对话框,点击保存正常下载,不会出现任何问题,当我我点击取消,服务器端就出现如下提示:

说明:

网上搜了一下,大致出现问题的原因如下:

1、这个问题一般是客户端在连接还没有完全建立的时候就取消连接,比如用户按了浏览器上面的“停止”按钮,一般来说没有什么问题。但是如果频繁出现,就表示很多客户端连接到Apache服务器的响应时间太长了,可能是网络的问题或者服务器性能问题 可能你的网络连接存在一些问题,你的数据传输的时候,可能由于时间等待的太久,但是server段设置的连接检验时间限制一定,那么就可能出现这种情况的! 
2、ClientAbortException: java.net.SocketException: Connection reset by peer: socket write error的原因是由于处理http连接时,正在输出内容时,用户关闭了IE,会出现一个"ClientAbortException",属于I/O处理中出现的一个异常,应用服务器应该会捕捉。

3、应该是线程被占用的太多了 无法控制了 
我想可能会是:数据库库连接达到极限,.应用服务器 最大线程并发数 达到极限,内存耗尽。

目前没有找到好的解决办法。。。
