my box runs fine .. but too much havp process.

Code:
ps aux | grep havp | wc -l
154
and there is the last scan job about havp.

Code:
11/06/2009 19:55:53 127.0.0.1 GET 404 http://220.231.142.4/4.Wma 182+1308 OK
11/06/2009 20:00:25 127.0.0.1 GET 200 http://isoredirect.centos.org/centos/5/os/i386/CentOS/thunderbird-2.0.0.18-1.el5.centos.i386.rpm 285+19307233 OK
but it's 22:16 now. nobody use squid now.
why havp can not kill overmuch process ??? waste memory...
