warning using check_dns

[Subhendu Ghosh]

A discussion this last week on the plugins list pointed to a new behaviour 
in 2.6.11 kernels in RHEL based systems for fork() that is causing these 
problems.

Reports like the one below are hard to diagnose if one does not provide 
context like plugin version, os version.  These things are requested in 
every message footer, yet seem to be lacking in requests for help.
