Not really. The point is that at the time the network card goes from up to 
down, named spits out this error. If you log named to a different log file 
then /var/log/messages, you will not see the relation. The reason for changing 
UP to DOWN can be from a device operating at the 2.4Ghz band when using 
wireless-g to someone bumping his elbow into the colo's network cable, driver 
problems to switch failures, etc etc.
