With watchdog timer firing at 250 ms, app watchdog timer firing at 30 s, and app timer firing at 6 s, every 235 s the app seemingly stops getting a callback for the 6 s app timer. 30 s the app watchdog fires and resets the MCU.
Disabling the HW watchdog and watchdog timer (the 250 ms one) seems to make this problem go away. Changing the app timer interval does not seem to have any effect.
