Note that growisofs attempts to increase the locked limit upon start-up 
and it even reserves for extra 4MB for code, data and stacks. Is it 
possible that extra 4MB is not sufficient for your system? Try to 
experiment with different values for ulimit -l/limit memorylocked, most 
notably `expr \( 32 + N \) \* 1024` with N > 4. A.
