koha at nelson:/usr/share/koha$ KOHA_CONF=/etc/koha/koha-conf.xml 
PERL5LIB=/usr/share/koha/lib ./bin/migration_tools/rebuild_zebra.pl -b -a -r
19:12:09-04/01 zebraidx(9447) [warn] MARC: Bad offsets in data. Skipping rest
19:12:09-04/01 zebraidx(9447) [warn] Record didn't contain match fields in 
(bib1,Local-number)

So -- just the two "warns".  Can anyone tell me if the "skipping rest" 
refers *only* to the one record, or if it aborted the whole 
re-indexing?  I'm guessing it aborted the process, as a quick look shows 
that none of the "missing" authorities have magically re-appeared.

Also, is the zebraidx(9447) referenced to the Koha biblio # 9447 (nothing 
appears amiss in it) or if there is some other way of finding which record 
is giving it indigestion?  I have no experience with zebra.

Many thanks - Paul
