I forgot to say that you might be getting these errors because you
limit the runtime of individual jobs to 60 seconds and that might not
be enough time for your mixed-a job to overwrite the entire 1GByte of
the file before it stopped due to running out of time. If later
verification jobs try to verify an area not written to, the header may
not be there or/malformed thus generating error messages.

Errors:
Multiple writers may overwrite blocks that belong to other jobs. This can
cause verification failures.
