Running the flow and refresh extract may fail on Tableau Server because of the failing backgrounder process.

Cause

The port of backgrounder instance was occupied by some other process(non Tableau Server process) and is in conflict.
Usually, 8000~9000 port range is reserved by default for dynamic mapping of Tableau processes.
So this issue also might occur on the other Tableau Server process.
Løsning
Check the ports used for Tableau processes with the following command. For this example, the port value of the issued backgrounder instance on node2 was 8888. 
tsm topology list-ports

Option 1

Stop Tableau Server, then work with your IT team to find out which process is occupying the same port that the issued backgrounder instance uses, then stop that process or bind it to a another port that all Tableau Server processes are not using.
You can check the port list on the inode to see which ports are used by the command below.
On Windows 
netstat -ano | findstr :8888
On Linux 
sudo netstat -apn | grep 8888

Option 2

Change the port number of backgrounder process to avoid the conflict with another process/system with the command below.

In this example, it sets the port for the first backgrounder instance on node2: 
tsm topology set-ports --node-name node2 --port-name backgrounder --instance 0 --port-value <value>
tsm pending-changes apply
