I think I've figured this one out. I had problems with my bibliographic records then. When I ran zebra index -b -a -r -x, there were four records not properly indexed. So this is where the problems occurred, such that when I export biblio records in tools, it stop in the problematic record. Remember the instance that I have to get the last biblio record I got during export and start to the next record (by +1 in biblionumber) and then it stops to a certain biblionumber, that was because of malformed/problematic biblio records. So when I deleted this records and re-run the zebra index and got no errors, I was able to export all of my records. -- View this message in context: http://koha.1045719.n5.nabble.com/exporting-bibliographic-records-tp5753557p...
