1 NIS is stopped.
2 NIS is starting.
3 NIS is running.
4 NIS is booting the local node (implies NIS is running).
5 The local node is booted (implies NIS is running).
6 The local node is synchronized (implies NIS is running and the local node is booted).
7 NIS local node does not see any remote NIS node (implies running and booted).
8 NIS is currently loading the block chain from the database. In this state NIS cannot serve any requests.


Code Desc
0 Neutral result. A typical example would be that a node validates an incoming transaction and realizes that it already knows about the transaction. In this case it is neither a success (meaning the node has a new transaction) nor a failure (because the transaction itself is valid).
