> ------from chris's post----------
> I'm running a set of ~50000 queries on one table, using inserts and updates, and i want
to be able to roll them back so i turned off autocommit using setAutoCommit(false).  As the
update runs, the memory used by the JVM increases continually until i get the following exception
about 20% of the way through:
> ERROR 40XT0: An internal error was identified by RawStore module.
