I'm using modem version mfw_nrf9160_1.3.1
It's waiting for semaphore and when CSCON notification came in between it's just resetting due to some hard fault. Can somebody tell me how to resolve this issue.

I had this problem before when I use malloc and I increased the HEAP_MEM_POOL_SIZE. It resolved my issue but I'm getting the same problem again.
my current configurations are
CONFIG_MAIN_STACK_SIZE=8192
CONFIG_HEAP_MEM_POOL_SIZE=4096
