Error when starting nova-network

Hi,
New to all this and trying to configure controller with an extra compute node.
Randomly the controller, server 1, loses connection to outside of the network, ie internet, and can't bring it back unless nova-network is ran, but it displays the following error.
Any help would be appreciated.

@controller:~# nova-network
