Bind CPU ussage issue

[Mike O'Hara]

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?
