Max cache size reached --> squid shuts down!!! help me

Okkay folks... I am running into this problem once every month or so!
I am looking for a solution!
I have configured squid to use 3 cache directories with different
size limit for each:

cache_dir /usr/local/squid/cache 100 16 256
cache_dir /data/squid/cache 2100 32 256
cache_dir /data1/squid/cache 7300 32 256

now... suddenly I notice that squid isnt running and users getting pissed
off... so I look in the cache.log and find the following:

2000/03/27 15:16:55| Starting Squid Cache version 2.2.STABLE2 for
alpha-dec-osf4.0...

Squid Cache (Version 2.2.STABLE2): Terminated abnormally.
CPU Usage: 0.053 seconds

so I do a du on the cache dir and find out it is near the limit I set
in the etc/squid.conf
file:

spider# du -sk /data/squid/
2043150 /data/squid/ <<<<<<<<<<<<<<-----------------

so I remove remove a small dir from the cache... just enough to
start squid again and
see the what the cachemgr.cgi has:

Indeed you can see that my /data/squid/cache is getting full!!!
Now I know that squid is supposed to do something when it reaches
the limit like overwrite certain old data... why isn't it doing
so?!?!?!?!why is it shutting down when the cache reaches the
maximum size I specified in the etc/squid.conf file?

this behavior is getting me frustrated.

any clues, help I appreciate it!!!

thanx,
