Updated to latest release and this device started scanning properly.

provisiond.log debug for rescan of this node.

Think this is what you need

Here is the provisond.log (in debug) for the rescan I just ran.... I snipped a few thousand INFO lines. There was no java stack trace in this log. If there is somewhere else to look for the stack trace let me know.
