lame servers resolving

[olga urbantimes net]

Since I am on the topic of logs... Here's another question.
I am getting a lot of 'lame server resolving' messages in the
/var/log/messages.

Here's an example:
Jun 24 09:02:25 isis named[1340]: lame server resolving
'71.68.90.80.in-addr.arpa' (in '68.90.80.in-addr.arpa'?): 80.90.64.38#53

Is this normal or does it mean that something is misconfigured or missing
in the bind configuration.
