check out note 199416.1 - talks about export corruption on certain releases.

This is just an idea based on past problems with the OCIs, but array
size (as in 'array fetch') is limited to 32K (smells of signed short
index). Your buffer size indirectly specifies the number of rows you
return with a single batch (something in the order of magnitude of
buffer / avg_row_len). It is not impossible, if your rows are short,
that your theoretical array size is past the limit and that Oracle
doesn't handle it properly.
