Thanks for the suggestions.
I already have logs to display all the exepctions and there is
nothing. I can't display the work done, there is to much :(
I have counters "counting" the rows processed and they match what is
done, minus what is not processed. I have just added few other
counters. One right at the beginning, and one to count what are the
records remaining on the delete list, as suggested.
I will run the job again tomorrow, see the result and keep you posted.
