nRF52 nrf_pwr_mgmt_shutdown restarts device immedietly

[sridhardv]

In our application we are using SDK13 with FreeRTOS by creating two tasks (xTaskCreate), in certain case one of the task need to shutdown the system.
We are using nrf_pwr_mgmt_shutdown(NRF_PWR_MGMT_SHUTDOWN_STAY_IN_SYSOFF) function but system restarts immediately.
We tried disabling and clear all interrupts and timers in our application but still controller is getting restarted.
We are using debugger so we added while(1); after the shutdown function call, by referring Nordic_forum.
Please help us to shutdown the controller, Is there any special steps need to be followed for application with FreeRTOS?
Can we have any example to shutdown the controller running application in SDK13/15 with FreeRTOS?

Seems to me that the wakeup source that you have configured the system to wakeup is always true. This will make the system restart as soon as you called nrf_pwr_mgmt_shutdown(NRF_PWR_MGMT_SHUTDOWN_STAY_IN_SYSOFF) . Please check the wakeup up source of your device and see if it is configured correctly and not true when the device is gong to system off mode.
