A teacher sent a message to a user. The logs shows that the student viewed the message and later logged out at 13:35 . At 13:47 until 23: 52 the logs indicate a systems event for this user:
"Web service function called. The web service function 'core_message_get_messages' has been called."
That is Sixteen thousand (16000) of these webservice function calls in a 10 hour period. How can i stop this.
We are running moodle 3.1.18 on an ubuntu server.
