If you rebuild your Linux kernel using Alan Cox's -ac patches (from
<URL:ftp://ftp.linux.org.uk/pub/linux/alan/2.2>), you get the ability
to dynamically alter the per-process file descriptor limit with
(u)limit, and go over the 1024 file descriptor limit which is hard
coded into the 2.2 kernel. Make sure you set the hard limit (e.g.
'ulimit -nH' with the bash shell) before building Squid.

Note that when you run ./configure you'll still see something like
this (for a hard limit of 8192) ...

  checking Default FD_SETSIZE value... 1024
  checking Maximum number of filedescriptors we can open... 8192

There's a bit in main() in src/main.c of Squid 2.[12] which says:

    if (FD_SETSIZE < Squid_MaxFD)
        Squid_MaxFD = FD_SETSIZE;

You can either comment this out (which is what I did) or hack at the
definition for FD_SETSIZE in your header files. If you don't, Squid
will report 1024 file descriptors.

It would be nice if Squid didn't do this, but I'm not sure what the
best approach is to fix it...

Sayonara!
