[squid-users] Squid Cache - hangs after a few minutes

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 ?

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
half a second per a page load, to 5 to 10, then 30 or 40 seconds..,
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???

I have turned off the firewall on the squid server as well as the
central apache server, and still doesn't help much. I read through
http://squidproxy.wordpress.com/2007...s-are-hanging/ and did all of
it, with no avail.

P.S. I doubt this is a connection issue between the servers, as the
website WITH squid loads just as fast as apache for a few minutes,
then slowly goes to a hault
