>
> Apparently sometimes the delete count in ACID stats doesn't match what merger
> actually returns.
> It could be due to some deltas having duplicate deletes from parallel queries
> (I guess?) that are being squashed by the merger or some other reasons beyond
> my mortal comprehension.
> The loop assumes the merger will return the exact number of records, so it
> fails with array index exception. Also, it could actually be done in a single
> loop.
