Can't enter app_sched_execute, is the scheduler blocked

Hi everyone, I am now writing a program with scheduler. But the program always can't enter app_sched_execute. I don't kow the reason. Is the scheduler blocked.

Firstly, in main I just initialize scheduler, such as APP_SCHED_INIT(0, 5);

Then, in for, for(;;) { app_sched_execute(); power_manage(); }

power_manage:
  static void power_manage(void) 
  {
    uint32_t err_code = sd_app_evt_wait();
    APP_ERROR_CHECK(err_code);
  }

I have a interrupt which has a 3s interval. when the interrupt happens, I just call the function(app_sched_event_put), such as app_sched_event_put(NULL, 0, test_example_sched_event_handler);

My program also have two timers, and the one interval is 1s, the other is 5s, with calling APP_TIMER_INIT and app_timer_create to initialize timer, app_timer_start start the timer.

The program run in the nrf51822. After 15 hours or longer hours, the program can't enter the app_sched_execute.

OK, so your program is blocked in some interrupt routine. That makes sense, that until it comes out of the while loop then it won't return to the main context where your app_Sched_execute needs to run. Seems like you have some issues with your TWI transactions.
