Make sure you are using ImageMagick Q8, it uses 100% less resources than the default Q16 version. Next try -limit memory 0 -limit map 0 and set your TMPDIR to an area with plenty of free space. If that fails, try the latest ImageMagick release, 6.3.0-0. It checks the memory and only buffers the JPEG image if plenty of memory is available.
