我有几个鱿鱼问题，但每次只解决一个：
警告！您的缓存已用完文件描述符
当代理收到大量呼叫时可能会发生这种情况，并且可以通过增加限制来修复，但我的甚至没有“打开“ 然而..
我发现它是鱿鱼以某种方式不断地连接到它自己？
（来自我的access.log）

我的配置最初是由 pfsense 创建的，但用于在 Ubuntu 20.04 上运行的独立鱿鱼。

其他奖励问题是：
2. 我需要一个http当我只使用 https/ssl 时的配置（端口 3128）
是的，显然这是必要的
acl 全部 src 全部（配置中的第一个命令）在系统日志中产生以下结果。这只是一个警告，但我该如何解决呢？
Aug 11 12:28:46 socks squid[2718]: WARNING: because of this '::/0' is ignored to keep splay tree searching predictable
Aug 11 12:28:46 socks squid[2718]: WARNING: You should probably remove '::/0' from the ACL named 'all'
- 如果您发现任何其他错误，请指出，如果可能，请解释原因（以便我们学习）。
答案1
在这种情况下，坏人实际上是一个被禁用的选项。
#tcp_outgoing_address 10.10.66.1
由于某种原因，squid 服务器显然不知道将输出数据发送到哪里，而是将其发送给自己，从而导致无休止的循环。
通过启用此命令，并将其指向我的外部 IP，通过这样做，可以避免环回。
对我来说，这将是一个不必要的命令，并且无法理解为什么它是必要的，鱿鱼应该知道互联网在哪里..
