[squid-users] Running out of filedescriptors

Hello Squid friends.

Recently I found in my cache.log this message:
   
    WARNING! Your cache is running out of filedescriptors

I found in the same file that Squid was using 1024 filedescriptors
   
I looked for that problem in the forum and FAQ and these are my steps to
resolve that:

(I have Red Hat Enterprise 3 Update 8, kernel 2.4.21-47.ELsmp, I have
Squid installed
from squid-2.5.STABLE14-1.FC5.i386.src.rpm)

Before compile src.rpm I changed these values:
   
    ulimit -HSn 8192

In the compilation I found:

    checking for strerror... yes
    checking for initgroups... yes
    checking Default FD_SETSIZE value... 8192
    checking Maximum number of filedescriptors we can open... 8192
    checking Default UDP send buffer size... 65535
    checking Default UDP receive buffer size... 65535

I reinstalled Squid with the new rpm:
   
    rpm -Uvh --force squid-2.5.STABLE14-1.FC5.i386.rpm
   
Squid is installed fine, the binary has a new date:
   
    -rwxr-xr-x 1 root root 745108 Sep 24 08:25 /usr/sbin/squid

I changed the /etc/rc.d/init.d/squid start section:
   
    echo -n "Asignando 8192 FD y otros valores"
    echo 1024 32768 > /proc/sys/net/ipv4/ip_local_port_range
    echo 1024 > /proc/sys/net/ipv4/tcp_max_syn_backlog
    echo 8192 > /proc/sys/fs/file-max
    ulimit -HSn 8192

    echo -n $"Starting $prog: "
    $SQUID $SQUID_OPTS 2> /dev/null
    RETVAL=$?

I started Squid but in cache.log I found again:
   
    With 1024 file descriptors available
   
Which is the missing or bad step?

I was reading the spec for squid-2.5.STABLE14-1.FC5.i386.src.rpm and I
found that file has a patch
for filedescriptors (option --enable-fd-config), this is the problem or
solution?

My squid -v:

Thanks for your help
