Re: [squid-users] Unable to increase filedescriptor limit -- tried all things

Hi Arana,

Thanks for your reply. As you are suggesting in your
reply that incresing the filedescriptor can be
dangerous. Is there any other way to get rid of this
warning, because this warning makes browsing dead
slow,and the box is deployed at our client place. I
have to do things fast. If you have any other
suggestion besides the increasing file descriptor
please suggest me.
