[CentOS] Bind on Centos4

[Tony Wicks]

Hi all, I have an issue with bind on Centos 4, I recently migrated one 
of my dns servers to a Centos 4 machine from a Centos 3 machine. The 
Centos 4 machine is running chroot, apart from that the configs were 
identical (both have caching-nameserver removed). The Centos 4 machine 
is very slow at initial lookups -

whereas a Centos 3.4 machine on the same subnet is running fine -
