Hi every one. I using squid version 3.1 at my work for Internet access. My squid doesn't want to run with more than 127 (exactly 127) authorization helpers. I have try to fix it by myself, but I can't anymore. I have approximately 500 users and some times squid simply goes down.
It shows me this in it logs.
Well, the problem is when i try to increase an amount of helpers,
it runs well for the first time, but when i try to reconfigure it, It stop working. And shows me this
After this I need to rerun it.
I'm sure that the problem is in my environment or system settings. Take a look at my system parameters
Here you can see that there is no any limit for fd
Maybe there is some parameters that i don't know?
PS: It happens with my home computer (FreeBSD 8.0-RELEASE ) too.
Many Thanks.
