maximum connectionsreached确认是不是tomcat线程数超了
在浏览器中输入http://ip:port/_index.html, 看访问是否正常

是否是哪里设置不对导致连接不能及时释放掉

----------还有就是一个客户端地址怎么同时有多个连接8080端口

1.在浏览器中输入http://ip:port/_index.html, 看访问是否正常
2.数据源的配置信息发一下看看
3.使用probe工具，以及操作系统自带工具
http://bbs.wex5.com/forum.php?mod=viewthread&tid=39228
查看当出现问题后，服务器的内存，CPU，线程，数据库连接使用情况;
4.一个客户端地址怎么同时有多个连接8080端口这个是什么地方监控的？
