Statuses:

  . --> Partition is ok
  X --> Partition is not ok (duplicates, missing, or nulls)
Comment 1 christian 2014-10-09 13:12:50 UTC
Since checking missings across hour boundaries does not make the
missing go away [1], it does not seem to be the race condition
described in bug 69615.

Since it seems only esams bits are affected, it might be another
instance of bug 71435.

More investigation needed.
