--- Comment #7 from Howard Chu hyc@openldap.org --- Note that if you wrote a lot of data in the txn, some dirty pages may have been flushed to make room for newer writes. In that case, any pointers to those flushed pages would be invalid. In that case, you'd have to use cursors to read the data reliably.
