Legacy ImageMagick Discussions Archive

I'm using imagemagick "convert" to convert pdfs to jpgs. Mostly it works great. But on larger files it seems to choke. My imagemagick version is:
Version: ImageMagick 6.5.1-0 2010-12-02 Q16 OpenMP http://www.imagemagick.org

Ghostscript version:
GPL Ghostscript 8.70 (2009-07-31)

This is the original command I used:

/usr/bin/convert -limit memory 0 -limit map 0 -density 150 -thumbnail 2000x2000 -verbose "/home/bnc/tmp.pdf[0]" jpeg:"/home/bnc/tmp.jpg"

Then I tried these variations:
convert -debug cache -limit memory 8192 -limit map 8192 -limit area 8192 -density 300 -compress zip /home/bnc/tmp.pdf /home/bnc/tmp.jpg

convert -debug cache -limit memory 0 -limit map 0 -limit area 0 -density 300 -compress zip /home/bnc/tmp.pdf /home/bnc/tmp.jpg

convert -debug cache /home/bnc/tmp.pdf /home/bnc/tmp.jpg

All of which produce this (see full error at the bottom):
convert: Postscript delegate failed `/home/bnc/tmp.pdf': No such file or directory @ pdf.c/ReadPDFImage/612.
convert: missing an image filename `/home/bnc/tmp.jpg' @ convert.c/ConvertImageCommand/2775.

Here is a link to the PDF:
