Hello,
I'm running bind 8.3.1 under red-hat Linux 7.1;
I was running it for months without any problem, but
from this afternoon I've noticed that named
is eating as much as 97% of CPU time; I've tried to
trace the problem , but without success,
enabling query logging I find queryes like :

or
07-Mar-2002 17:50:44.727 queries: XX+/62.10.69.159/adsweb.tiscali.it/A/IN
07-Mar-2002 17:50:44.727 queries: XX+/62.10.92.230/y1.extreme-dm.com/A/IN
07-Mar-2002 17:50:44.727 queries: XX+/212.123.67.27/portal/A/IN
07-Mar-2002 17:50:44.728 queries: XX+/212.123.67.123/eurolada.com/A/IN
07-Mar-2002 17:50:44.729 queries: XX+/212.123.67.121/www.laserpen.nl/A/IN
07-Mar-2002 17:50:44.729 queries: XX+/212.123.93.124/106.93.123.212.in-addr.arpa/PTR/IN

my named.conf file contains the options :

options {
directory "/etc/named";
pid-file "/etc/named/named.pid";
query-source address * port 53;
notify yes;
fetch-glue no;
max-ncache-ttl 600;
listen-on { 195.130.225.129; };
lame-ttl 300;
recursion yes;
use-id-pool yes;
allow-transfer { interni; };
allow-recursion { utilizzatori; };
version "la mia versione";
cleaning-interval 20;
rrset-order {
class IN type A name "tiscalinet.it" order cyclic;
class IN type A name "tiscalinet.com" order cyclic;
class IN type PTR name "225.130.195.in-addr.arpa" order cyclic;
};

};

do you have an advice for my case , or can somebody tell me what shoul I search into
log files ?

thanks
