Linux端口占用问题

loveyou_1108

我的Linux服务器上要使用一个数据通道,也就是说这个服务绑定在tomcat下运行.tomcat是8080这是正常的,只是这下面绑定的这个服务是端口提示下面错误;
当然我把下面的端口改了也会出现同样的情况,而且用netstat -an 会查看我以前绑定的服务在端口都会占用,就是说我用8686占用再用8888还是占用
不管用什么都会占用,而且netstat -an  以前使用的如8686端口8888一样都会被监听.  请问这个问题怎么解决?(要说明的是,我在另一个机器上运行是可以的.我想问一下是不是会系统有关系?) 说的繁琐了点,不知道你们的听懂了吗? 其实我也不好描述这种情况
