Description Craig 2021-02-02 15:32:49 UTC 
Unsure if this is a bug, but:

Koha 20.11 + ES6 + Ubuntu 18.04 + MariaDB (also running Plack)

Searching authorities using /opac-authorities-home.pl on my OPAC returns an Internal Server Error if one tries to navigate past page 500, whether the index to search on is set to Default, Topical Headings, Personal Name, etc.

I am referring to here: https://library.craigbutosi.ca/cgi-bin/koha/opac-authorities-home.pl 

I have about 420,000 authorities in my repository, which I mostly uploaded from the Library of Congress. A few hundred of these have been imported via Z39.50. This translates to about ~21,000 browsing pages.

This behaviour only seems to happen with ES, not Zebra. Is this a memory issue, timeout issue, or something else? I can't quite find anything in the error logs.
Comment 1 Katrin Fischer 2023-01-23 23:17:32 UTC 
I can still confirm the described behaviour in the linked library catalog that is now using 21.05. But I don't have enough data for confirming in newer versions, can someone help out?
