原因

ClientAbortException

直观上来说，就是客户端已经退出了，服务端还在向客户端写数据。

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。

客户关掉了浏览器，而服务器还在给客户端发送数据

客户端再发起请求后没有等服务器端相应完，点击了stop按钮，导致服务器端接收到取消请求（频繁的刷新就会产生此问题）。通常情况下是不会有这么无聊的用户，出现这种情况可能是由于用户提交了请求，服务器端相应缓慢，比如业务逻辑有问题等原因，导致页面过了很久也没有刷新出来，用户就有可能取消或重新发起请求。这种错误是合理范围内的，无法避免的，不必关心它。

Tomcat服务器在接受用户请求的时候，有其自身的处理能力，线程、服务器等各个资源限制，超出Tomcat承载范围的请求，就会被tomcat停掉，也可能产生该错误

Linux的线程机制会产生JVM出错的问题，特别是在连接高峰期间经常出现这样的问题，tomcat在linux下也出现类似情况

界面多次出发请求，后台请求尚未处理完的情况下会发生（属于单个浏览器的多个接口并发）
