Two points:

         - do you have any duplicate 001 Control Numbers? [1] This was our 
biggest difficulty after upgrade from 3.6.1 to 3.8.5 [001 should be unique 
when taken in conjunction with 003, but zebra does not respect this.]

         - did you follow reindexing the authorities with the 
biblios?  ./bin/migration_tools/rebuild_zebra.pl -b -r -x

Best - Paul

[1] You can verify this in mysql with:

SELECT GROUP_CONCAT(biblionumber SEPARATOR ', ') AS biblionumbers,
EXTRACTVALUE(marcxml,'//controlfield[@tag="001"]') AS id FROM biblioitems
GROUP BY id  HAVING count(id) > 1
