I compiled and installed bind9.5.1b1 (without threads)on solaris 9 in
an ultrasparc machine with 2cpu`s 900 Mhz and 4G Ram.
unfortunately,after few hours,named process consumes heavy load from
cpu:
PID USERNAME SIZE RSS STATE PRI NICE TIME CPU PROCESS/
NLWP
1064 root 109M 107M cpu2 59 0 2:23:45 93% named/5
then some queries responded and some queries dont respond.
Here are my named.conf:
options {
version "version not currently available";
pid-file "/opt/namesurfer/run/named.pid";
directory "/opt/namesurfer/named/namedb";
dump-file "/opt/namesurfer/named/namedb/named.dump";
recursive-clients 65536;
statistics-file "/opt/namesurfer/named/namedb/statistics";
tcp-clients 32768;
};
logging {
channel simple_log {
file "/var/adm/named/bind.log" versions 3 size 50m;
print-category yes;
print-severity yes;
print-time yes;
severity warning;
};

category d
efault {
simple_log;
};
};
controls {
inet 127.0.0.1 port 953 allow { 127.0.0.1; } keys
{ "rndckey"; };
};

Does it relate to logging options?
i removed it from named.conf,,but bind sent logs to syslog and the cpu
problem existed?!(is this default for bind 9.5.x?how can we disabled
this default state?)
How can i solve this heavy cpu load problem?
