[squid-users] squidaio_queue_request: WARNING - Queue congestion

hi all..

in my squid log i've found some line like this :
"squidaio_queue_request: WARNING - Queue congestion"

and i'm search in my squid source dir, i've
that error message in
src/fs/aufs/aiops.c
//begin
    if (request_queue2.head) {
        static int filter = 0;
        static int filter_limit = 8;
        if (++filter >= filter_limit) {
            filter_limit += filter;
            filter = 0;
            debug(43, 1) ("squidaio_queue_request:
WARNING - Queue congestion\n");
        }
    }
//end..

could somebody englighten me.. what's meaning for..
am i doing something wrong in configure my squid ?..
eg.. configure with too many AUFS_IO_THREADS perhaps
?.

I'm using squid-2.5PRE7
and kernel 2.5.18 (I'm needed ide driver for
via vt8233a and promise pdc20276 so i'm
stuck with beta linux kernel)

my configure options as follow :
before that i'm setting environment vars
export CFLAGS="-O6 -s -DNUMTHREADS=50"
ulimit -HSn 16384

./configure --enable-dlmalloc --enable-async-io=50
--enable-poll --enable-arp-acl --enable-snmp
--enable-removal-policies --prefix=/usr
--exec_prefix=/usr --bindir=/usr/sbin
--libexecdir=/usr/lib/squid --localstatedir=/var
--sysconfdir=/etc/squid
--disable-ident-lookups
--enable-linux-netfilter

i'm using 2 cache dir each at separate hdd,
one at /dev/hde1 and second at /dev/hdg1
what's the most optimum setting (number of
aio_threads) for each hdd / cache_dir ?

thanks..

regards

Budi Aditya
