根据上面的报错信息解读:

org.apache.catalina.connector.ClientAbortException: java.net.SocketException: Connection reset:表示客户端在服务器完成请求处理之前就关闭了连接。

查找网上资料,发现大部分提示是:

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

误打误撞,查看了下Linux下载文件的目录磁盘大小,发现已经满了,于是将其迁移掉,腾出下载空间,再次下载成功.

原因分析:

1.当服务器下载目录磁盘空间不足时,应用程序无法写入新的数据,导致了写入操作异常,服务器将文件发送客户端,写入失败,后续输出流操作失败.

2.下载文件的时候,需要将文件数据写入网络连接,若空间不足,则可能会抛出异常,导致客户端连接被重置

3.客户端由于等待文件生成时间过长,可能会因为超时而断开连接,随后服务器继续发送数据会抛出异常.
