Hi to, I'm trying to use ElasticSearch everywhere with Koha 20.11 I'm working on Debian 10, EleasticSearch 6.8.13, Java openjdk 11 (Debian package) The search on Opac and Intranet is OK. Problems are on z39.50 server. With bug 13937 a z39.50/SRU server is ready also with ES as search back-end. But now the demonization of the script doesn't work. If i do: sudo koha-z3950-responder --start lib and I do a check with: yaz-client Z> open 127.0.0.1:2100/biblios Connecting...OK. Sent initrequest. Target closed connection Z> The result is 'closed connection', ZOOM error: 1004 But if do: sudo koha-z3950-responder --stop lib sudo koha-shell lib /usr/bin/perl /usr/share/koha/bin/z3950_responder.pl -c /etc/koha/sites/lib/z3950 -l /var/log/koha/lib/z3950.log koha@deb:~$ yaz-client Z> open 127.0.0.1:2100/biblios Connecting...OK.

So the script 'z3950_responder.pl' is working, the transformation into daemon not. Do you have any suggestion/check to fix this situation ? Cheers Zeno Tajoli -- Zeno Tajoli System Librarian
