cache_dir size weirdness

I'm running 2.2-STABLE4 (previously STABLE3) on FreeBSD 3.3-STABLE and
I just noticed something odd about my cache. From the beginning, I've
had my cache directories set up like so:

cache_dir /cache.0 6000 16 256
cache_dir /cache.1 6000 16 256
cache_dir /cache.2 6000 16 256

But I've noticed that each cache_dir never seems to grow past about
1.2GB of usage.

Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/da0s1g 6625221 1251550 5307419 19% /cache.0
/dev/da1s1g 6625221 1252212 5306757 19% /cache.1
/dev/da2s1g 6625221 1252062 5306907 19% /cache.2

All this time, the following line in the logs has been escaping my
eye:
Sep 29 10:01:56 cheetah squid[40163]: store_swap_size = 3697752k

Does this log entry specify how much data is currently in the cache,
or the maximum cache size?

I don't think anything else in my config could affect the cache
directories and how much they can hold, except possibly a larger
maximum_object_size of 8192K.

Any ideas?
