Are you sure ?
Maybe it should be
instead of "blind9" .
Code: Select all
named=blind9=dns server
Code: Select all
bind9

i'm not sure how your short & cryptic replies are supposed to be helping here.
assuming you really need named, you have to fix it.
if you don't, you just remove it from your services or make sure it does not run.
given the lack of info provided, i cannot be less cryptic than you.
of course you could also hire me, then i would come over and could really look over your shoulder.
you have to find out what named does, why it eats so much cpu, then correct the behavior.m0o0hammad wrote:What can I do to reduce CPU?
