[squid-users] Cache Partition Problem

Hi,
I have Four (4) partitions for my cache directory and occasionally one of
the cache directory will get full and low disk error is displayed and
squid stop responding to request. After some times or days squid rebuilds
and said cache directory is free of space, why?
Why is squid keeps rebuilding most of the time?
Is there any configuration option to adjust the cache dir re(building)
operations?
Below is extract from my cache log.
Regards,
Yomi.
