A user is being used in an external module and attempts to connect with invalid credentials.
Search for the usage of the user object. If not used in an object inside the Automation Engine or ARA - JOBS, JOBP, EVNT, you will need to search for connections from external applications attempting to connect via a CallAPI or a third-party application using the Java API.
Once the culprit has been found, ensure the user credentials it uses are valid.
