"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 ..."

I killed squid with killall ?!
I don't think so. killall does nasty things to the child processes
inside Squid. Best to avoid it.
You can kill -HUP the parent process by itself. Which is the same as
"squid -k shutdown", and passes the skill signal to the squid child
process after some initial cleanup.

First to restart I send killall -HUP squid. What happened ?!
You killed Squid before it completed writing and setting ownership
details for the new swap.state file.
Erase the swap.state file and start Squid again as you normally would.
Have some patience this time because the startup may take a long time
to regenerate the content of swap.state from on-disk information.
