[Koha] Elasticsearch reindex failing for authorities

[Aleisha Amohia]

Hi all,

We have a site with around 600,000 authority records and have enabled
elasticsearch. Reindexing and searching has worked easily for biblios
(there are just over 10,000 biblios) but fails for authorities.

$ sudo koha-elasticsearch --rebuild -d -a -v <instance>
[19024] Checking state of authorities index
[19024] Dropping and recreating authorities index
[19024] Indexing authorities

And then it just hangs there for ages until the server runs out of
memory and dies.

We're running ES 6.x on Koha 20.05.x.

I tried running the script directly and specifying an authid and that
worked as expected.

$ perl /usr/share/koha/bin/search_tools/rebuild_elasticsearch.pl -a -d
-v -ai 2135575
[17684] Checking state of authorities index
[17684] Dropping and recreating authorities index
[17684] Indexing authorities
[17684] Committing final records...
[17684] Total 1 records indexed

It feels like this is happening because we have too many authority
records. Is there a way to fix this? Has anyone come across this before?

Thanks!
