Problems with Squid 1.1.20

We have been running Squid 1.1.20 on FreeBSD for a couple of weeks now ...
until now it has been running perfectly ... We have the cache being stored
on a 8gig drive, but when it reached 32% full squid started reducing the
size of the cache. The hard drive light is now always on and the space used
will not go above 2.2 gigs (the computer has 128megs of RAM). Here is my
squid.conf file:

http_port 8080
debug_options ALL,1
acl all src 0.0.0.0/0.0.0.0
acl tocache proto HTTP FTP
http_access allow all
icp_access allow all
cache_mem 80
cache_mem_low 75
cache_mem_high 90
cache_swap 7900
cache_swap_low 90
cache_swap_high 95
cache_effective_user squid squid
cache_effective_user nobody nogroup
cache_dir /drive2/cache

Here is what top saids, before yesterday the CPU for squid would not go
above 1% :

 PID USERNAME PRI NICE SIZE RES STATE TIME WCPU CPU COMMAND
  145 root -6 0 17952K 18000K biowai 1:03 7.44% 7.44% squid

Any ideas on whats its doing?

Thank you,
Jason McKay.
