Hi Ioana
Thanks for the test!
Do we actually expect errors when running such a test? How many times
have you run this test and seen any of the error counters be anything
other than 0?
Which do you think is more likely:
1) A real error happens
2) Bug in the driver so that it reports a value in the wrong place?
Maybe we should check the error counters are zero?
Andrew
