terminating connection due to administrator command

Hi, today I had a problem with mi Postgres Database, for some reason I receive this message in console, I don't know what it means, the only thing I know is the DB started to malfunction. A user makes a normal change in ONE element (using the frontend web application) and the database did not work properly and changed the information of 7,000 items in the database 🥲, what happened to my database and why it started malfunctioning ? Each single update updated all 7000 records. When I redeployed the db the problem was solved
