About eight years ago I tried to convert a bunch of scanned lecture
notes (~70 jpg files) to a PDF, and discovered that ImageMagick has a
memory leak.  I was able to complete the conversion by adding a few
large swap files:

  dd if=/dev/zero of=/tmp/swapfile bs=1M count=2000
  mkswap /tmp/swapfile
  swapon /tmp/swapfile

I wonder if you've stumbled upon the same bug, still not fixed in eight
