Hi, I am writing with a request for help. It is about a causing a problem when searching for records by z39.50. (Koha version: 20.05.05.000). On the printscreen ( ibb.co ibb.co ) you will see responses for the following messages and one or two search results. It looks like it cannot retrieve some records. There are no errors in the intranet-error.log. The address of the server z39.50 from which I am searching for records is: hostname: eu.alma.exlibrisgroup.com:1921 database: 48OMNIS_NLOP I testing in yaz-client but when I show all records then yaz is stopped in Sent presentRequest. yaz-client -f conf_bn Connecting...OK.
