I had a consultant check out some issues with SAP B1 and Fourth Shift Edition, as part of the troubleshooting he setup a notification server which sends error messages. Periodically error messages come through, a couple of times messages kept coming through every minute. I ended up rebooting the server. I just wondered if anyone knows what these means? I called the consultant back but have not heard anything The email subject is "SERVER_NAME\SAP BLOCKED X SESSIONS - IP ADDRESS". I have attached a print of the email.
