MarkG (Customer) asked a question.

What causes RTE-121 Action Overflows?

I've got a project running on a CM5-RHMI. It's been running fine for a month or so, but now my customer is seeing RTE-121 Action Overflows at the top of the screen. The only mention I can find about this in the C-More documentation is "The number of actions executed in the event exceeded the maximum number." but that's not particularly helpful. What event? How can I control the number of actions being executed in the event?

    Is there an answer for this? Same issue. Not sure how to proceed?

      Does the panel's System Screen.Information.Errors indicate any event that would cause this?

      Poking in the dark as I have not experienced this.

      I believe firmware v8.22 solved this issue for me.
