I have SunFire V880 (2 cpu +4G Ram) and installed bind 9.6.1-P1 on solaris
but my cpu load is very high!(above 90% during the pick time)
bash-3.00# prstat -a
PID USERNAME SIZE RSS STATE PRI NICE TIME CPU PROCESS/NLWP
562 root 2517M 2498M cpu0 0 0 1503:30:2 95% named/5
2394 root 3808K 3168K cpu2 59 0 0:00:00 0.9% prstat/1
here are some relatde information:
recursive clients: 841/9900/10000
My input traffic which shown by MRTG is about "2.5" Mbps recieved
requests(udp 53) and is normal in our network behavior during the pick time.
my question is:
does this high cpu load relate to input requests and is normall or it relate
to something else?
also i disabled dnssec(dnssec-enable no;dnssec-validation no;) & Logging
feature in bind,
but the cpu load didnt decrease!
anybody have idea about it?
