Strange DNS behaviour between the primary and the secondary

Hello Managers,

My primary nameserver is a Tru64 box running 5.1 and BIND 8.1.
My secondary nameserver is a Tru64 box running 4.0G and BIND 4.9.3

I have a sub domain with the following line in /etc/namedb/hosts.db on the
primary :

sub 86400 IN NS public.sub.supelec.fr.
public.sub.supelec.fr. 86400 IN A 160.228.200.xy
sub.supelec.fr. 86400 IN A 160.228.200.xy
public IN CNAME public.sub.supelec.fr.

and I have no problem to satisfy reverse query on this primary server, as
by example xy.200.228.160.in-addr.arpa.

with the following line in hosts.rev

200 IN NS sub.supelec.fr.

On the secondary side, I have the following lines in hosts.db

public 86400 IN CNAME public.sub.supelec.fr.
sub 86400 IN NS public.sub.supelec.fr.

and in hosts.rev

200 86400 IN NS sub.supelec.fr.

When I try a reverse query on the secondary, the answer is :

*** secondary.supelec.fr can't find xy.200.228.160.in-addr.arpa.: Server
failed

200.228.160.in-addr.arpa.

gives ;

Authoritative answers can be found from:
200.228.160.in-addr.arpa nameserver = sub.supelec.fr

Is there some incompatibility between these 2 versions on Tru64 or is there
something else ? Or perharps it's not a Tru64 questions...
