After running OracleBulkUpdateHandler.prepareBulk successfully on a ~2 GB RDF dataset, I get an OracleDatabaseException during completeBulk. Any idea why this would happen?

The completeBulk flags I'm using are "PARSE PARALLEL=4 PARALLEL_CREATE_INDEX MBV_METHOD=SHADOW DEL_BATCH_DUPS=USE_INSERT MBT_JOIN_HINT=USE_HASH MBV_JOIN_HINT=USE_HASH".

Here is the full stacktrace:
