上述问题分析:

在网上查找了了下原因，大概归结为： 

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。 

Connection reset by peer的原因： 

经常出现的Connection reset by peer: 原因可能是多方面的，不过更常见的原因是： 

①：服务器的并发连接数超过了其承载量，服务器会将其中一些连接Down掉； 

②：客户关掉了浏览器，而服务器还在给客户端发送数据； 

③：浏览器端按了Stop 

 

        很多人都说是客户端造成的,没有办法控制,而且后台会记录这个异常，日志也会疯狂爆满,时间长了,肯定会DOWN掉的.
