LinuxQuestions.org - Squid cache setup? Need some advice

Im trying to get multiple squid servers to act as front-end web servers for my main central apache web server, here is my setup so far...

I have changed the IP of the apache server that this sends traffic to, to 123.123.123.123, fyi

Code:

# egrep -v "^#" squid.conf | sed -e '/^$/d'

acl all src 0.0.0.0/0.0.0.0

acl manager proto cache_object

acl localhost src 127.0.0.1/255.255.255.255

acl to_localhost dst 127.0.0.0/8

acl SSL_ports port 443

acl Safe_ports port 80                # http

acl Safe_ports port 21                # ftp

acl Safe_ports port 443                # https

acl Safe_ports port 70                # gopher

acl Safe_ports port 210                # wais

acl Safe_ports port 1025-65535        # unregistered ports

acl Safe_ports port 280                # http-mgmt

acl Safe_ports port 488                # gss-http

acl Safe_ports port 591                # filemaker

acl Safe_ports port 777                # multiling http

acl CONNECT method CONNECT

http_access allow manager localhost

http_access deny manager

http_access deny !Safe_ports

http_access deny CONNECT !SSL_ports

http_access allow all

icp_access allow all

http_port 80 accel defaultsite=123.123.123.123 vhost

cache_peer 123.123.123.123 parent 80 0 no-query originserver name=myAccel 

cache_peer_access myAccel allow all

hierarchy_stoplist cgi-bin ?

cache_dir ufs /var/spool/squid 2000 16 256

access_log /var/log/squid/access.log squid

cache_log /var/log/squid/cache.log

acl QUERY urlpath_regex cgi-bin \?

cache deny QUERY

refresh_pattern ^ftp:                1440        20%        10080

refresh_pattern ^gopher:        1440        0%        1440

refresh_pattern .                0        20%        4320

acl apache rep_header Server ^Apache

broken_vary_encoding allow apache

always_direct allow all

coredump_dir /var/spool/squid

This works wonders.. for about 4 minutes. then the requests go from 2 seconds per a page load, to 5 to 10, then it wont even process, the tail -f access_logs shows that its not even hitting apache any longer on the central server, so its like squid freezes up, any idea???
