[squid-users] almost 100% CPU usage

Hello all,
I'm new to squid and I'm trying to configure and use this proxy server.
I'm working on a Debian 3.0 updated system on an Apple Mac PPC.

My configuration file... I've copied the default squid.conf and removed all
the commented things I do not have configured. This is the resulting file:

cache_peer 10.0.0.5 sibling 6588 3130 default
cache_peer 10.0.0.1 sibling 6588 3130 default
hierarchy_stoplist cgi-bin ?
acl QUERY urlpath_regex cgi-bin \?
no_cache deny QUERY
cache_mem 8 MB

It happens that, as soon as I make a request that is not available through
the cached things, the squid process goes to about 97-98 CPU percentage.
I've tried to touch the /dev/null file as described in the 11.46 FAQ
section but it doesn't work.
Is there someone who can help me in solving this problem?

Thank you,

Marco Bresciani
