Squid Crashes when cache dir fills

["Wilson Hernandez - MSD, S. A." <wh@xxxxxxxxx>]

Hello.

I have experienced some sort of crash with squid. I noticed that when 
the cache directory fills up, squid stops caching, it only allows 
communication through with the messenger and users start getting the 
unable to redirect message on the browser.

If I delete the directory and create it again squid -z then everything 
works fine.
