Dear Community;
I have a NRF9160 DK. I have flashed a program to it, and it works fine. The program connects to LTE every 10 minutes to send some data over HTTP. However, after 1 day working:
err = getaddrinfo(host_name, NULL, &hints, &res);
that line crashed:
Exception occurred in Secure State
***** HARD FAULT *****
Fault escalation (see below)
***** BUS FAULT *****
Precise data bus error
BFAR Address: 0x50008120
***** Hardware exception *****
Current thread ID = 0x200201a8
Faulting instruction address = 0x29d34
Fatal fault in ISR! Spinning...
What is causing the fault?
This is my prj.conf file:

I am using ncs tag 0.4.0
Any idea or suggestion is welcomed!
Thanks.
