Comment 19 for bug 1668876

Thanks to Rob this is now fixed.

All occurrences were due to mistaken manual re-runs. We will implement safeguards to avoid this mistakes to have such impact again.

The script run to check integrity in Jerff was sucking too much IO on an already heavily loaded machine, so we could not finish the validation.

I will revisit this bug in a few days and mark it fix released if no other issues come up.
