Leds Serial Gateway all flashing every second

[Petjepet]

Hi,

I have my Serial Gateway on a RasPi with Pimatic operational for >2 years now.
Since a few days I notice all drie leds (rx, tx, error) are flashing simultaneously every second.
I can recall it didn't behave like that when I setup the system.

All is working correct, I see all sensors sending/receiving data in a correct way.

What can be wrong here?

@petjepet the debug log will probably be the quickest way to find out
