Why does the EUM processor fail to start with port 7003?

[Amit.Jha]

Problem

The EUM processor fails to start if provided with port 7003 for the EUM processor, even though the port seems free using the following command:

netstat -an | grep 7003

The issue is due to port 7003 being used internally as the admin port. This configuration is defined in the local-eum-processor.yml file within the <EUMHome>/eum-processor/conf directory:

adminConnectors:
- type: http
port: 7003

Therefore, there will be a conflict for this port when the process is starting up. The processor will fail and show a net bind exception in the logs.

Solution

Use a different port for EUM HTTP/HTTPS other than 7003, or change the YAML configuration file to select a different port for internal use of EUM.
