BUG !? swap.state: (13) Permission denied ...

["Riccardo Castellani" <ric.castellani@xxxxxxxx>]

I'm using Squid 2.7 Stable in Debian Sarge environment, when I tried to 
restart Squid service but process died.
I got this message in cache.log : "swap.state: (13) Permission denied ..."
First to restart I send killall -HUP squid. What happened ?!

Now I restored swap.state file owner because owner was root while it should 
be proxy.
