[LUNI] Broken Pipe using growisofs from scripts

[jcbailey at code0.net]

I'm getting a pretty cryptic "broken pipe" error when running growisofs
from a script. I've tried the same thing in PHP, Python, and in Bash, but
still get the error. The odd thing is that if I run the same command from
an open shell, it runs just fine. I've also tried running the scripts as
root and still couldn't get it to work.. I haven't found anything useful
from Google... Any ideas?


Command:
growisofs -dry-run -M /dev/sr0 -R -J /DATA/DES_temp/BATCH1/*


Output:
Executing 'mkisofs -C 16,2240 -M /dev/fd/3 -R -J ***CUT OUT A BUNCH OF
