#Raspberry (here: ZeroWH)
#LEDBlink 1 seconds

My Internetradio program (Raspberry Zero WH) crashes on a few devices after a while and the LED blinks ~1 blink per seconds.

On the Internet I could not find a clear indication what this might indicate.

Does anyone know what the reason could be in this case?

Current PI OS LITE (32 bit).
Bluetooth is disabled, bluez software stack removed, tempfs is on RAM, swapsite 0 Byte. Very fast and good SD card.
