[hobbit] Re: WARNING: Runtime longer than time limit / DNS Timeout

[Rich Smrcina]

The ARES library in some older (4.2) releases of Hobbit had problems.  
Check the archive for details and other potential solutions.  Can you 
ping this machine by it's IP address?  If so, I would temporarily change 
bb-hosts to test this host by IP only.
