NVBU server has changed it's preferred address
Description

Some or all client backups may fail and some of the following messages can be found in the logs.
Channel '00000000014C5B60': process ID '2' connected to process ID '132' running on 'CLIENT1' has been lost.
NetVault Backup running on 'CLIENT5' has not responded to messages
NVBUSERVER1 has changed it's preferred address from 10.10.50.23 to 10.10.150.42
Cause

If another NetVault Backup server is setup with the same NetVault Name, it will broadcast its information and replace the information for the original server. The messages look like communication errors, but the problem is that it is switching between each of the servers to send data to based upon which was the last to broadcast its information.
Resolution

You can't run two NVBU servers with the same name at the same time. The best solution is to reinstall one of the NetVault Backup server and give it a different name.
If the second NetVault Backup server with the same name needs to remain, it cannot have network access to the any of the clients or the NetVault Backup service needs to remain stopped.
