I don't know what's happening with squid but this kind of CPU consumption is
just not normal:


last pid:  9761;  load averages:  0.98,  0.97,  0.83     up 0+19:23:06  13:23:42
50 processes:  2 running, 48 sleeping
CPU: 97.3% user,  0.0% nice,  2.4% system,  0.0% interrupt,  0.4% idle
Mem: 595M Active, 250M Inact, 107M Wired, 6508K Cache, 95M Buf, 26M Free
Swap: 1023M Total, 1304K Used, 1022M Free
