named[4120]: socket.c:1100: unexpected error:

[news.comcast.giganews.com]

While reoragnizing some rackspace we moved our DNS server last night and
then rebooted it again tonight, as part of switchign which UPS it is plugged
into.
After rebooting it tonight we started seeing the following errors.
Everything else on the server appears to be running OK.

I am running bind 9.2.1 on RH Linux 9. I have added the -d3 switch to get
more debugging information, but no error messages are showing. Anyone have
any idea what might cause this? The problem occured right after tonights
power down (shutdown -h now) and restart.

I am at my wits end as to what might be causing this. I am unable recognize
any clues that might point to the cause of this problem. Any assistance
would be appreciated.
