[squid-users] 100% cpu

I've checked the FAQ and read over the archived messages over this (I
realize it's a common topic), but nothing has helped yet.

Running squid-2.4.STABLE6-6.7.3 on a redhat 7.3 box. Using transparent
proxying via a cisco router and iptables. As soon as it starts caching,
the CPU jumps to 100% and stays. It doesnt do it every 5 minutes etc,
it's just constant. The performance SEEMS to be ok with it, but it
still worries me for obvious reasons. Below are the only changes I've
made to squid.conf:

http_port 3128
httpd_accel_host virtual
httpd_accel_port 80
httpd_accel_with_proxy on
httpd_accel_uses_host_header on

cache_replacement_policy heap LFUDA
memory_replacement_policy heap GDSF

cache_dir aufs /raid/cache 100000 30 256

cache_access_log none
cache_store_log none
redirect_children 10

Any ideas?
