thanks for all the ideas

the core problem isn't the size of the export file - it's that the lobindex on the lob column is corrupt. I just mention the export size since it seems extremely unlikely to me that the data for this table really occupies over 2gb. It is of course possible that it is since dba_segments won't report the size of the lob in the size of the table, but still 5000 html docs shouldn't really be 2gb in size..
