Hi, you can activate the full debug launch squid -k debug with the service running, and check what comes in the cache.log.
squid -k parse will audit your config file. Look for WARNING in the output of this command. the cachemanager can be usefull to see the actual activity of your squid : squidclient localhost mgr:5min gives you the last 5 min stats. (see if the n° of req/s is coherent with what you expect ) Bonne chance Alex 2013/3/26 Youssef Ghorbal <d...@pasteur.fr>: > Hello, > > We have a Squid 3.1.23 running on a FreeBSD 8.3 (amd64) > The proxy is used to handle web access for ~2500 workstations and in > pure proxy/filter (squidGaurd) mode with no cache (all disk caching is > disabled) > It's not a tranparent/intercepting proxy, just a plain explicit proxy > mode. > > What we see, is that the squid process is using 100% of CPU (userland > CPU usage, not kernel) all the time.
