我使用nginx作为反向代理来将一些stream量redirect到openfire XMPP服务器。 以下是我在netstat中看到的内容：
972 connections to port 80 from outside (includes website and redirected XMPP over http) of them 231 in TIME_WAIT, seems like normal 272 connection from localhost:<misc port> to localhost:7070 (nginx to xmpp server), all ESTABLISHED 3154 connections from localhost:7070 to localhost:<misc port> (xmpp back to nginx) of them 2882 in TIME_WAIT (1301 of them with expired timers) seems like it's not normal! 为什么有这么多？ 如何摆脱这种联系？
