Nona has run out of memory. There are some parts that could be optimized 
a bit more. In an unfortunate case, nona can need twice the
memory that is needed to store on panorama image (when remapping to 
multiple tiff).

One image of size 14456x7228 needs 14456 * 7228 * 4 bytes = 398,6 MB of RAM.

Try using a smaller output size, and it should work better.
