Return code: 1
What causes the error
I have been successfully running this code on datasets stored locally. The error appeared when we switched to processing a dataset from a NFS mounted storage.
See similar error at https://mail.python.org/pipermail/python-list/2009-July/543694.html
Solution
Until now, we did not find a solution for processing with success the dataset stored on the NFS mounted drive.
Workaround
Make a local copy of the dataset to be processed
