My bet is that on the WRTs, unbound is crashing because it is running
out of memory. You could change the init script to be something like:

 	while true
 	do
 		unbound -d -c /etc/unbound.conf
 	done

I'd login and run this in a shell to confirm:

 	while true; do cat /proc/meminfo; sleep 30; done
