I think i've discovered a problem : one of our clients has a DB with daily
serials that are itemised. Thus, we reach up to 600 items for a given biblio.
when reindexing zebra, I get a nasty "
18:51:38-03/08 zebraidx(31045) [log] add grs.marcxml.record

"

Investigating the data, I've discovered that the record is more than 99999Bytes
long. Thus, xml (marcxml) handle it properly, but the iso2709/marc is incorrect
& zebra really don't like that.

We can't fix the iso2709 behaviour, so we have 2 possibilities :
- fix Koha to limit the size of a biblio/items (check that we don't ge more
than 100kB)
- fix the export during rebuild_zebra.

I think the 1st solution is the best.
