iPhone 7 rebooting - panic bug type 210

My wife's iPhone 7 is sporadically rebooting a couple of times a day.

I have found several logs in Settings - Privacy - Analytics - Analytics Data.

One of them is panic-full-2019-01-23-183144.746.ips

This is the start of this file:

It seems the kernel is panicking but I cannot determine the cause.

Can anybody help?

Thanks
