各位大神，squid文件描述符保留很大 怎么回事呢？

eydns

Reserved number of file descriptors:  18463（别人这里都是100，我的运行几分钟后这里就变得很大，文件描述符就不够了，是怎么回事呢？我已经改为了20480的总数了，但就是保留很大，不够用了）

大哥你在搞笑吗？这个已经很明显的告诉你文件描述符当前只用了1950。

你下面说的那个参数是保留的文件描述符，默认文件描述符是1024，保留的是100.为何保留变大了，自己改了什么设定。另外squid我们最大习惯修改为16384

    经过检查，发现是内部路由器和交换机的IP设置一样了 改后保留就好了。

  你说得对只用了 1000多，就是只用了1000多squid就提示不足了
