'memory allocation failed' with convert.exe

[ElScorpio]

Hi,
I use ImageMagick to convert some jpeg files into a multi-pages pdf file. I use the command: convert.exe file1.jpg file2.jpg - adjoin file12.pdf
It works if I try to convert 4 or less documents, if I try to convert 5 or more, ImageMagick convert the 4 first and I got the message:
Magick: memory allocation failed 'C:\..._005.jpeg' @ error/jpeg.c/ReadJPEGImage/1113
What can I do to resolve this problem?
I use 6.6.3-Q16 version

Thanks

Thanks for your response, but I have a little problem: when I want to convert 6 jpeg files black and white or grey level) into 1 pdf, I have only 4 pages in my pdf w. When I want to convert 6 jpeg files (256 colors), I have a 6 pages pdf file (60 MB) but the last page can't be displayed and I have this message:

Magick: unable to extend cache 'C:\..._006.jpg' No space left on device @ error/cache.c/OpenPixelCache/4163
Magick: application transferred too few scanlines 'C:\..._006.jpg' @ error/jpeg.c/EmitMessage/235

I post here the result of the command ' identify -list ressource'
File: 1536
Area: 21.401 GB
Memory: 14.949 GiB

I took a look at your link but the -limit option seems to, as its name said, limit free memory to the application and not allocate more memory.

What command have I to use to get more memory and to transfer enought scanlines.

thanks

ImageMagick trades memory for temporary disk space. Set your temporary file path to a partition that has plenty of free space. See http://www.imagemagick.org/script/archi ... tera-pixel.
