Slow Squid response times..

Hi,
        Just a problem I have noticed over the past 24 hours or so. Our
cache which compromises of the following :
Intel Celeron 350
256 meg RAM
1 9g UW scsi
1 9g UW scsi
1 18g UW scsi

The cache is very slow to serve requests, even local sites are a dog to
come down. To fix it, i restart squid, and all is fine again, however
give it another couple of hours or so, and bang! it starts to respond slow
again, version is 2.3.STABLE1-hno.20000202 with the latest snapshot from
Hendriks site

Any ideas??

I havent rebooted the machine as of yet.
