Detailed explanation of the problem:

Hi there,
I got the error message from apama.
I have several analytics builder models running. And it looks like, that one of them generates a problem.
Even if this model is running since a couple of weeks.

Any idea what it could be?

Question related to a free trial, or to a production (customer) instance?

We a using the could enterprise solution of Cumulocity.

Hi Oliver,

there were maintenance activities on 20th of June in that timeframe. I suspect that the apama-crtl microservice was shortly unavailable in your tenant during that maintenance but should be fine now as maintenance was successfully completed.

okay. I understand.
But why are some builder models still running and one not?

What I am doing here is a simple scale of measurements.
I can see that the measurements(from the edge device) is changing, but the builder model is not converting them into another measurement?!?

Now we turned off and on the edge device and everything works again.

Looks like during the maintenance process of you yesterday, something is stuck.

Is there no restart of the system after the maintenance?
