Multiple Named Daemons on one machine

I'm trying to setup a Split-DNS on a single machine having one network
interface. I've created an IP alias for the network interface & have
created the following directory structure:
//var/named/int// Internal DNS server file directory
//var/named/ext// External DNS server file directory
I've setup the respective zone files & named.conf file in each
directory.
I can run multiple daemons of named from command line as follows:
/usr/sbin/named -u named -c /var/named/int/named.conf -t
/var/named/int
/usr/sbin/named -u named -c /var/named/ext/named.conf -t
/var/named/ext
But I'm unable to start these daemons from the startup script which is
as follows:
--------------------------------------------------------------------------------
#!/bin/sh
#
# named This shell script takes care of starting and
stopping
# named (BIND DNS server).
# ----------------------------------------------------------------------------
# Source function library.
. /etc/rc.d/init.d/functions

# Check that networking is up.

[ -f /etc/sysconfig/named ] && . /etc/sysconfig/named
[ -f /usr/sbin/named ] || exit 0

When I run this script, I get the following errors in the logs:

--------------------------------------------------------------------------------Both
the files /var/named/int/named.conf & /var/named/ext/named.conf very
much exist.
Cannot figure out at all what's causing this problem ?
Any idea/suggestions/solutions are very much appreciated.
Thanks,
Ashwin.
