cache limit warning

 Hello everybody,
 I run squid 1.2 beta19 and all the time
I get the following messages in the cache.log file:

1998/04/19 14:06:14| WARNING: Disk space over limit: 323411 KB > 307200

  I've defined 300 mb for cache in the squid.conf file as:

cache_dir /usr/local/squid/cache 300 16 256

 And I see that cache really uses above 300mb.

 How can I prevent that or it's a bug?

 Thanks.
