Can you compress the data enough that I can try a blend on my machine?
I'm thinking scaling each image a factor of two, and then compressing
each with jpeg with a low quality setting. I'll blow them up again and
attempt the stitch. If that works here, I'll have to instruct you to
try to stitch the blown-up version.

I can provide an FTP account if you need one.

You tried running without imagecache and it didn't die "without
reason". the OS refused a memory allocation because it couldn't find
any more memory for you to use. What happens if you:

	dd  of=swapfile if=/dev/zero bs=1M count=16k
	mkswap swapfile
	swapon swapfile

Maybe the stitch simply needs more than 24Gb of memory?

        Roger.

Title:
  enblend fails to blend large pano

Status in Enblend:
  Confirmed

Bug description:
  Enblend failed with:

  enblend --compression=LZW -m 1200 -w -f135659x3947+0+1091 -o pano8110_l.tif ....
  ...
  enblend: info: loading next image: pano8110_l0000.tif 1/1
  enblend: out of memory
  enblend: std::bad_alloc

  This is a simple 0.5Gpixel panorama I shot. And agreed, Hugin did warn
  me that it might take a lot of memory.

  The thing is: There is no other tool to stitch this with, so I'll have to make do with hugin and its toolset....
  I thought there was an "imagecache" that would swap parts of images to disk...
