May I ask you why you set max_prepared_transactions to 450, while

records are
written to the database in a single transaction.
Did you perhaps use 2PC at first, but didn't bother to change the
config after switching to the last agent optimization?
Yep.. one of the things that we didn't revert back and got strayed out
