KB485344: "Invalid Port Number" error occurs while configuring the Intelligence server

Description

When configuring the Intelligence server via the Configuration Wizard, the following error appears: 
[ERROR] Invalid Port Number: The port 34952 you specified is in use, please use another one. 

Solution

• Check which processes occupy which ports using the following command: 
  

  
  sudo lsof -i -P -n | grep LISTEN
  

  
  In the following example, the

  MSTRSvr 20252

  process occupies the

  34952

  port. 
  

• To use the port (for example,

  34952

  ) while configuring the Intelligence server, kill the process using the command:
  

  
  kill <process number>

  
  In this case, it is: 
  

  
  kill 20252

  
  
• Check if the processes were killed for the given port. 
  

• Continue with configuring the Intelligence server.
