run a cron job to restart Squid once a week?
or simply not using tons ov regular expressions within squid access lists
and leave the job to external program(s).

Thanks list for help.

restarting squid is not a solution, I noticed only after 20 minutes
after restarting, squid started consuming/eating CPU again.

Nor I re-compiled Squid, as I have to use binary/rpm version of squid
that shipped with the Distro I am using

issue resolved via removing acl that blocked almost 60K urls/domains

commenting following worked
##acl porn_deny url_regex "/etc/squid/domains.deny"
##http_access deny porn_deny

so how can I deny illegal contents/website ?


If those were actually domain names...
 * use "dstdomain" type instead of regex.
* use wildcard sub-domans where possible: .example.com instead of a.example.com plus b.example.com ...

Optimize order of ACLs so do most rejections as soon as possible with fastest match types.

If you don't mind sharing your squid.conf access lines we can work through optimizing with you.
