Probably due to the fact that the name server has received a recursive 
query (query coming from a client resolver) for data that resides in a 
zone for which the name server is not authoritative.  With 'forwarding' 
configured this behavior is normal.  However, if another name server where 
to ask, it would get the referral and follow the delegation.  You may want 
to consider not using forwarding...
