[squid-users] Very high CPU load

Hello,

for a few days I have a strange problem with
squid running under FreeBSD. Although the proxy
is almost not used squid runs all the time with
99% CPU utilization.

Have already rebuilt the complete cache dir and
installed the latest version (2.5STABLE3) nothing
changed the situation (rolled back to 2.5STABLE2 again).

Below some information about the system and software.

Did anybody have the same phenomenon or has an idea
what can be the resaon (or better) the soluion?

##### squid version #############
Squid Cache: Version 2.5.STABLE2
configure options: --bindir=/usr/local/sbin
--sysconfdir=/usr/local/etc/squid --datadir=/usr/local/etc/squid/
--localstatedir=/usr/local/squid '--enable-storeio=ufs diskd null'
'--enable-removal-policies=lru heap' --enable-auth=basic
--enable-basic-auth-helpers=SMB '--enable-external-acl-helpers=ip_user
unix_group' --enable-underscores --prefix=/usr/local i386-portbld-freebsd4.8
