I can't repeat step 2 on demand, but I'm already trying to capture traces for this ticket so I'll try to kill the connection if I see the odd CEREG status go by... (The other ticket is more urgent since it was causing the application to lockup. This one was more of a curiosity by comparison...)

Hi again!

Could we get a modem trace from you for this situation?

See this tutorial on how to retrieve a modem trace.

Best regards,

Heidi

Just saw retry number 6 at hour 5! It appears to be backing off exponentially.

I need need to reboot my nRF9160, so I can't let this run any more. But honestly, 5 hours is already too long IMHO.
