How large is your cache_dir?

Most likely this object has been revalidated with the origin server and

Squid is supposed to keep your cache_dir at the configured size.

Most often this type of problem is due to not have configured log
rotation, causing Squid to use wast amount of space for logs (including
swap.state).

Don't know.

Please look into

   a) Your cache_dir configuration

   b) What inside your cache_dir is using this much space, if possible.

   c) Version of Squid used.
