If you are a system administrator in your WorkBook, you will most likely receive error messages like these from time to time.
This doesn’t necessarily mean that something is wrong in your WorkBook, but it’s just an information to you (as a system administrator) that one of the many configured agents in your WorkBook at some point didn’t run as expected. You can open the attached log to get at hint on what went wrong.
In the agent setup, you will see which agents are active in your WorkBook. Some of these agents run as frequently as every 5 minutes (or 288 times a day) so there are a lot of automated tasks to take care of by the agent engine. And sometimes an error occurs. Usually the error will disappear again the next time the specific agent runs. So unless you get the exact same error every day – or several times on the same day – there’s no need to worry.
As per default, all system administrators in WorkBook will receive these error messages. If you don’t want them, you can remove your own WorkBook ID from system variable 800.
