May I ask you why you set max_prepared_transactions to 450, while you're
apparently not using prepared transactions, according to this quote:
Recoverable 2-phase transactions were used to coordinate the interaction between
the database server and JMS server using Sun's Last Agent Logging
Optimization; the 1PC database transactions and transaction log 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?
