[Question] What causes the Polling overload?

[henjoe]

I have one MQTT client device, and I just added topics to subscribe, every time I deleted a tag, a warning of Polling overload always happen.

My question is what causes the overload?

Thanks and regards,

Hi, polling it means that there is a task that reads the tags of the device at a certain interval and overload indicates that the reading has been longer than the interval of the next polling task.
