Cryptic error message from xorriso

[lists.cdwrite@duinheks.nl]

Hello,

I'm trying to run xorriso with the folowing command:
growisofs -M /dev/hdc -R -J -V Daily Daily *.Monday.*

Before that I did:
export MKISOFS=xorrisofs

It starts running: 
Executing 'xorrisofs -C 16,152384 -M /dev/fd/3 -R -J -V Daily Daily bin.Monday.txz boot.Monday.txz dev.Monday.txz etc.Monday.txz home.Monday.txz lib.Monday.txz opt.Monday.txz root.Monday.txz sbin.Monday.txz usr.Monday.txz var.Monday.txz | builtin_dd of=/dev/hdc obs=32k seek=9524'
GNU xorriso 1.0.2 : RockRidge filesystem manipulator, libburnia project.
Drive current: -outdev 'stdio:/dev/fd/1'
Media current: stdio file, sequential
Media status : is blank

But then it fails with an error:
...
Added to ISO image: file '/var.Monday.txz'='/Backup/Regular/var.Monday.txz'
xorriso : UPDATE : 12 files added in 1 seconds
xorriso : aborting : -abort_on 'FAILURE' encountered 'FATAL'
xorriso : NOTE : -return_with SORRY 32 triggered by problem severity FATAL
:-( xorrisofs has failed: 32

I would like to know what this error means, bu have not been able
to find anything about it.
Help please!

Thanks in advance,
Regards,

	Hans.
