KNX telegram overload stop knx communication

Hi, im looking for someone have more expertise or same issue im facing with.

I discovered that, with a flow that sends a KNX telegram every minute to any component, Homey, after a certain period of time, stops communicating via KNX. any knx instruction or incoming telegram fails. Has this happened to you or is it a known problem? could it be a limit of the knx?

thanks una Advance
