If you fill up your squid cache, CPU will go to 100% but the cache will not be cleaned up. I ran into this on my local cache. You can find info here: http://www.squid-cache.org/Versions/v2/2.3/bugs/#squid-2.3.stable3-storeExpiredReferenceAge Fix: Apply referenced patch. How-To-Repeat: Fill up your squid cache - cpu will max out.
