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

Check ./squid -v ; see what it was compiled with.
Make sure you start squid after you change the default ulimit.
Either put "ulimit -n 8192" at the top of the squid startup
script or find the place where your default ulimits are set
and modify that.
