Re: High CPU usage after installing ISC BIND ver 9.3.1.



Hello Herb,

Thanks very much for the reply. Let me brief the situation. These two DNS
servers are being setup after AD migration activities has been done as
replacing the old WINS servers. All the migration and BIND installation are
done by other person/group. As I am doing monitoring on these servers I
figured the symptom caused by ISC BIND.

May I know what is exact version of your BIND running on your Win2K3? and I
believe you have same "named.exe" process running in the task manager and How
much CPU usage that particular process takes on yours?

Thanks again Herb.

Hi,

Good day. My name is Amir. I really need any helps from you guys on this.
Two of our client's DNS servers which are in Win2K3 been installed with
ISC
BIND version 9.3.1 and since then CPU usage of both servers' hits nearly
99%
and drops back to 0% intermittently . I figured out that a process called
"named.exe" that related to ISC BIND is the reason which contributed most
to
the CPU usage.

Named.exe IS "BIND", the service itself.

Thus, I downgraded the version to 8.4.4 for one of the server
and as result the symptom got disappeared and I am planning to downgrade
ISC
BIND version for the server as well. The question is, by downgrading the
ISC
BIND version will this give any harm to server's performance or something?

This is not a "BIND" newsgroup but I have some (random) thoughts
on running BIND:

BIND 9.x and 8.x are really separate products in many ways and
are NOT sequentially different versions (i.e., 9.x is NOT an upgrade
of 8.x) -- so you have weigh the features you hoped to gain from 9.x
and determine if 8.x can offer those to you.

I have run various versions of BIND 9.x on Win2000 and Win2003 servers
with no problems.


And what are the advantages to have latest version of ISC BIND installed?
Any
explaination or suggestions are very much appreciated.

Why are you running BIND when Windows Server has its own
built-in DNS service?

(There are reasons for running BIND but if you don't even know
the feature differences between 8 and 9 it is not very likely that
you really need BIND rather than Windows DNS.)
