Squid only thinks it has stored 178943 KB (the Current Size entry).

The filesystem has some overhead which adds to this, and maybe you have
a core file from a Squid crash or a huge swap.state index (grows large
if Squid is running for a long time without rotating log files)

One way to find out if Squid is correct in how much it has stored is to
count the number of bytes stored in the cache directories:
expr `find /usr/local/squid/cache03b/?? -type f -print | xargs cat | wc
-c` / 1024
