Vehicle Tracker NRF9160 Radio Sometimes hangs, we have initiated a nightly reboot which uses alot of battery. How can we avoid the radio hanging?

We have designed a vehicle tracker that uses the NRF9160. We have found in the past that sometimes after the radio has been running for a while it gets into a loop where it becomes unresponsive, basically a loop where it doesn't receive messages.  We have to reset power to get it to work again. We are using the Asset Tracker 2 as our base code.

We added a nightly reboot to try to refresh the radio every night before it has a chance to hang. I was told that this solution can be bad for battery usage.

What are the best practices for the NRF9160? Can just the modem be reset if needed?

Thank You
