Here is an unknown actor in my audit database, name "5". But it does not exist in my user source. So what could it be? I don't have vision module.

Does the text in the action column offer a clue? What populates the variables of the insert query?

This text is from a specific script where I have customized the action with system.util.audit. This only means that the script is triggered. Maybe someone pressed a button, maybe a timer triggered the script, but neither should be this actor.

Alter that script to check for an invalid actor, When encountered, generate and log a fake exception to get a backtrace of where it originates.
