I saw this same warning on a new Nagios server.  If you are like me, it 
was related to an apparent bug in the Redhat RHEL kernel.  (I think it 
was the kernel, anyway)

Regardless, the solution is to download and compile the check_dns plugin 
from source.  If it detects it is on a system with the problem, it 
implements a workaround.  My system works fine again after doing this.
