Diagnosis
The statistical data is written to a cluster table. There is only a
certain amount of space for data in each row of the cluster table.
If a table row does not provide sufficient space, continuation rows
are written in the cluster table. All of these rows have a sequence
number, starting at 0. Each row also contains a field that contains the
amount of data stored in the row. All rows except the last row contain
the maximum value (2886) in this field; only the length of the last
row can deviate.
A probably-bad entry is a data record for which the last continuation
row also has the maximum length. This can be a sign that one or more
additional continuation rows may be missing. However, since the highest
continuation row counters are also missing in this case, it is
impossible to determine for sure. The probability that a data record
of this type is bad is around 99.965%.
