We have FreeRTOS running on ARM M4. After running the application for a while, the RTOS Tasks seem to restart without the MCU resetting. What could cause this?

That is not normal :slight_smile:

I would first check the regular things, as described here.
Make sure that all task stacks are big enough, make sure that configASSERT() is defined. Could there be a relation with interrupts or exceptions? What about the Watchdog Timer? Are you sure it isn’t causing a reset? Can you put a break at the beginning of main(), or even earlier?
