I experienced this same problem. The problem is that Zebra still has those records indexed, even though they no longer exist. Running rebuild_zebra.pl will not help. I tried dropping the database. I tried uninstalling and reinstalling Zebra. I even tried uninstalling and reinstalling Koha. Didn't work. I looked around some more and finally found some files in /var/lib/koha/zebradb/, which is where I now suspect that Zebra stores its indexes. I deleted the /var/lib/koha/ directory and reinstalled Koha again and the problem was solved. There may be a better way to do it, but that is what worked for me. //SIGNED// PERRY OTIS Systems Librarian Muir S.

We reimported my bib records as well as the authorities, and this time I am happy to say that the migration bulkmarc & bulkauthority utilities seemed to work without any trouble! So I had thought that all of the little nagging problems that plagued us after the first installation were cleared up. However... now, when I search my OPAC, I see redundant records (2 or 3 identical records), and also when I click on some search results I get an Error 404/not found message. We already tried dropping the database a second time (so I have run the web installer, reset all of the preferences, and imported the MARC and authorities twice in the past 3 days) and still I have this redundancy and error 404 problem. I also just tried running rebuild_zebra, and received this error: DBD:mysql:st execute failed: deadlock found when trying to get lock: trying restarting transaction... at line 240". I don't know whether this rebuild error is related. Any ideas you can offer would be appreciated! Thanks Amy C.
