weird - CP detection should run without problems at this size - in fact it was 
not too long ago that autopano was automatically reducing images to a similar 
size when detecting.

purely for a preview, you can change the output size in Hugin's stitcher tab.

if you already did the job of stitching full size and you want a smaller one, 
use ImageMagick:

convert input.tif -resize 50% output.jpg

from my experience, these issues happen when memory is low and image size is 
large in relationship to it.  Might have been a memory leak somewhere.  
Projects that I stitched about a year ago with enblend 3.2 showed the issue on 
a 2GB laptop and no issue on an 8GB desktop.  With enblend 4.0 even a 2GB 
machine works through them successfully (although: it's no longer the now 
defunct laptop, but it is a nettop).
