ADC server problem?

I’m not seeing a wide number of radio not responding issues, I’m actually only seeing a couple examples occurring around the same days.

There is a similarity in your two cases in that both are at 2.5.2 firmware IQ Panel 2+. That is a very common firmware version right now, but you also have the same hardware revision. It may be good to update after the power down to the latest 2.5.5.
