ither it stops completely or the replies would take a very long time. I'm =
running Bind 8.3.4 on an E3000 SUN server with 1.5 GB of memory and 4 CPUs=

utilized while the 3 other CPUs would be idling more than 80% of the time.=

lized? Anybody got a clever solution for my problem? Any help is greatly a=
