Check permissions on the executable?  Is your normal user allowed to
execute it?

According to 'man mmap', EAGAIN means the file is locked (inmpossible
for an anonymous map), or too much memory has been locked.  Presumably
that number is the number of bytes it's trying to mmap().  Check the
output of 'ulimit -l'.  On my system that's 32kB for both my normal
user and root, which clearly isn't enough (haven't tried growisofs
here).  Maybe those limits aren't supposed to apply to root, though
that doesn't explain what's going on in your situation.

I do seem to remember a while ago using growisofs on another system it
complained when I tried to run it as root (see the growisofs manpage,
'NOTES' section).  Not sure if that's part of the problem, either.
