squid的问题Unsupported method

Question

请教各位一个问题：

    现我架设了一台代理服务器，系统是redhat9，用的
squid-2.5.STABLE12.tar.gz，自己编译的squid
以前一直用的很好。今天早上起来突然不能用了
查看log信息
/var/log/messages中没有报错信息

最后两行应该就是错误信息，但网上找不到关于P8NET的描述
想请教一下。到底是什么原因？如何解决？

Answer 1

寒一个。发现不是上面的问题。
实际上是文件描述苻老是自动改成1024
我ulimit -HSn 8192也没用，过一段时间又自动改回来了，现在只能在crontab里让每个小时自动执行一次
ulimit -HSn 8192
不知道这是什么原因呢？

Answer 2

路过。
没见过此类现象。关注中。。。

Answer 3

没人吗？

Answer 4

我手动在ie选项里指定代理没有问题
就是做成透明网关时有此错误

Answer 5

最后一行是怎么回事？
是被黑了？
