jamesd256:

Perhaps your problem is that you're running populate_tables in both runs, giving you some duplicate records. Maybe it would work if you remove the populate_tables from the first pass? On re-reading the node, it appears that I'm mistaken and that you've already separated out the distinct records. However, does your XML split script perhaps include all "dependent" records (as in a foreign-key relationship)? If so, perhaps it's one of the foreign key tables that includes duplicates.

Alternatively, perhaps you can examine your schema that XML::RDB generated, and use XPath queries to split out the XML into individual tables, and then process the smaller files individually on a per-table basis?

Update: added CPAN link, added italicised section after re-reading OP.
