Hi Morrie -
The "unable to locate node" message happens when something outside of the client (usually network) temporarily drops the clients connection. Another cause is when an application running on the client blocks the streaming http connection - Fiddler (http://www.telerik.com/fiddler
) is a common culprit on windows.
Another common cause is when the hostname in the configuration is wrong or the bucket doesn't exist (if I remember correctly).
