Consistent error message in named.log

Is there a way to see from the primary master named server side to see
what the client is trying to update? The /var/adm/syslog/named.log
output just shows some basic NXDOMAIN information failing, so we just
want to see what subdomain or domain name it is trying to update.
We have somewhere in the range of 75 virtual firewalls so looking at
each one is really not an option.

This is a FAQ.
Q: I keep getting log messages like the following. Why?
Dec 4 23:47:59 client 10.0.0.1#1355: updating zone 'example.com/IN':
failed: 'RRset exists (value dependent)' prerequisite not satisfied
A: DNS updates allow the update request to test to see if certain
met prior to proceeding with the update. The message above is saying
conditions were not met and the update is not proceeding. See
rfc2136.txt for more details on prerequisites.
Also prerequisites are processed before any acls according to RFC 2136
is why you see these even when updates are denied for everyone.
