weird occurance with cache_dir -- squid1.2.23b + 4 patches

Hi. I've noticed something weird happen with this. A few days ago, I added
an extra cache_dir entry to my squid1.2.23b + 4 patches.

cache_dir /usr/local/squid/cache1 6000 16 256
cache_dir /usr/local/squid/cache2 6000 16 256
cache_dir /usr/local/squid/cache3 6000 16 256
cache_dir /usr/local/squid/cache4 6000 16 256

cache4 is the one added.

2 days on, it looks like that drive is being filled.

Filesystem 1024-blocks Used Available Capacity Mounted on
/dev/sdb1 6102297 5020373 765847 87% /usr/local/squid/cache1
/dev/sdc1 6133291 5013172 802436 86% /usr/local/squid/cache2
/dev/sdd1 6102297 5009268 776952 87% /usr/local/squid/cache3
/dev/sde1 6102297 2411798 3374422 42% /usr/local/squid/cache4

However, taking a look at the cache manager output

Its certainly using Store Directory #3, but i'm baffled as to why the
Maximum Swap Size is still saying 18Gb, instead of 24Gb, and am not sure
whats happening to the data being written to cache4 :) Is there some upper
limit with squid1.2b23 ?

I had a look in the FAQ, and found
http://squid.nlanr.net/Squid/FAQ/FAQ-4.html#ss4.14 which states you can
add/remove cache_dir lines ok, but didn't find anything about limitations
on cache sizes.

Any ideas?
