blade-vm hwoarang # /etc/init.d/squid restart
 * Stopping squid ...
squid: ERROR: Could not send signal 15 to process 2489: (1) Operation not permitted
 * Squid shutdown failed, probably service is already down.               [ ok ]
 * Starting squid ...    

Even running /etc/init.d/squid stop does not work. The process is still running

Anything funny when you run squid -X -k shutdown on your console?

Also please check your cache_effective_user directive in squid.conf and check which user id your Squid process is running under.

When running -X -k shutdown I get this

cache_effective_user is set to "nobody" and squid is running as root (using the init script)
Comment 3 Markos Chandras (RETIRED) gentoo-dev 2013-01-27 14:45:47 UTC 
Fixed by swithing the cache_effective_user from "nobody" to "squid". It should have been a permission problem on my side.
