挑战Apache和Tomcat连接问题，非高手勿入！

snakerlee 2003-03-18 10:26:16

采用mod_jk2整合的Apache和Tomcat，运行一段时间后无法访问（如同down机）
这时通过8080端口能够正常访问网站！
如果停掉tomcat,这时Apache也能够正常响应404错误（Apache正常）
但就是不能通过Apache访问Tomcat!!!
如果重启Tomcat就可以正常访问，原因何在？？？

但是隔一段时间，这样的连接就会达到256的最大连接数，造成无法访问。
什么原因呢？

不是中毒,这是用来apache与tomcat通讯用的.

用来连结的端口要重新用一个新的,不要用已用的.
检查你的httpd.conf连结tomcat的配置是否正确

用来连接的的端口是8009，我用8080访问的是tomcat本身提供的服务。
我插了一下连接，发现以下的情况，高手是否知道为什么有这么多连接？
