Problem with Squid on Linux machines

Hi,

I work at an ISP and we use Squid as our proxy server on Linux boxes (all are
Pentium Pro, 256MB RAM, 12GB HD). But after Squid runs for a week or so, the
filesystems are seriously fragmented (non-continous rates > 20%) and the
machines get slower and slower. Has anybody else encountered such a
behaviour? And what about FreeBSD? Does Squid run better on this system?

BTW, we use Squid 1.1.20, Linux 2.0.32, ...

Best regards,

        Oliver Andrich
