"killall" does this:

  * killall signal -HUP shutdown to child 'squid' process
     -> child process begins shutdown cleanup procedure.

  * killall signal -HUP to master 'squid' process
     -> master process signal -HUP to child process
       -> child process receives double-HUP "abort shutdown NOW"
       -> child process abandons all system resources and aborts
shutdown cleanup actions.

Use "kill" not "killall". Or best to use "squid -k ..."
