NAMED: annoying error in syslog

Hi list.
I managed in having DHCP and BIND interacting in order to update zone 
files as soon as a lease is released.

Everything works fine, but I have an annoying (it's just my point of 
view) message in /var/log/syslog, where dhcpd and named are logging.
Here is what I see:
> Aug 27 09:34:06 cnsrv010 dhcpd: DHCPDISCOVER from 00:11:d8:ec:cc:f9

The annoying line is:
> Aug 27 09:34:06 cnsrv010 named[13071]: client 127.0.0.1#32869: 
> updating zone 'farmol.it/IN': update unsuccessful: CNWKS2K034

I'd like to know the meaning of this message, if this is just a normal 
log or is due to a configuration error.
BTW, the host CNWKS2K034 is already listed in the zone file before named 
tries to do its job.


TIA for any hint.
