So what exactly happens when it fails to connect?
   
  If I enable verbose, the following prints will be there in the log
   
  "not connected.
  Closing connection #0"
   
  ( When the connection fails the application will try connecting again)
  
What libcurl version on what operating system?
  
libcurl 7.15.5
  OS linux 2.4

There's a 60 second DNS cache, but I doubt that is the reason here.
