Hi Preetish,

On a Linux box, that should have worked right away. I assume that they
should also work for BSD boxes too. By the way, as Henrik mentioned, did
you verify the binary run /path/to/sbin/squid -v

What do you get when you issue the following 2 commands:

limits

and

ulimit -n

On your OpenBSD machine, I was wondering why your file descriptors is
only 1024 in the first place.

On BSD systems, I think increasing the following sysctl tunables might
help in general for a busy machine:

kern.maxfiles
kern.maxfilesperproc

Set those values to say 8192 or higher and save it in either your
/boot/loader.conf or /etc/sysctl.conf in case of a reboot.

Hope it helps.

Thanking you...
