Bind CPU ussage issue

I saw this on my Linux system when I had configured Bind ACLs to use the
internal NIC instead of the external NIC even though most queries were
to come through the external.  Changing to the external NIC resolved it.

Subject: Bind CPU ussage issue

I am having a helleva time managing Bind on my server.

Server Specs are

Dual Xeon 2.66 GHZ
1 Gb ram
Windows 2003 Server
ISC Bind 9.2.2

Now Bind will regularly spike up to 100% CPU usage and stay there
untill the named service is restarted. then it will work its way back
up there again after a non descript period of time.

Is there a configuration glitch that is causing it to eat CPU cycles
like they are going out of style? or will upgrading to the latest
release solve my issues?
