You started a DataPump schema import with parameter REMAP_SCHEMA. This apparently hangs indefinitely on "TABLE/STATISTICS/TABLE_STATISTICS". You verified, the patch for <Bug 5071931> is installed but the import is still slow. If you exclude the statistics (EXCLUDE=STATISTICS) or do not use REMAP_SCHEMA, then import is very fast.
