I spoke too soon.
The error has reared up again. This time on a 3dTstat command in a different dataset and without scripts running in parallel.
For whatever it is worth: The numbers below ++ WARNING are identical to the previously reported error. I suspect they reflect i/o buffer size and initialization.
All the best,
Ziad
