Dear Mr. Battistoni,
        I am sorry for reply your email later because I have deleted all
completed jobs from our farm. In order to
re-appear the errors, I re-run all the jobs on farm these days. I run
about 90 jobs and two of all appear such errors.
Every job has 50 cycles. There error jobs can complete but no data
output. Please see the attachments.
       Thank you very much!

                                          Best regards,
Hantao Jing
