Morgan,

This appears to be the same problem we're experiencing on RHEL6.  This 
bug WAS fixed in bind 9.8.2rc2 AND the final 9.8.2 BUT Redhat decided to 
use 9.8.2rc1 as the base for their bind package.  I can't shake my head 
enough trying to figure out why they would use a release candidate but 
that's what was done.

Anyway, Redhat is working on a patch for this and it should be released 
"soon".
