Diagnosing sudden increase in CPU usage (no images)
by Justin Dowswell 30 Apr '26

30 Apr '26

Hey everyone, Was hoping for some guidance on where to start diagnosing an increase of CPU, disk and network usage on our Koha instance. The culprit is seemingly plack (/etc/koha/plack.psgi) & the Koha perl API (usr/share/koha/api/v1/ app.pl). No changes were made, updates nor configuration, and according to our monitoring started on the 23/03. Have gone from sitting at around 0% CPU idle, to ~20% on the 23rd and now averaging around 70%. Any ideas on where to start? Thanks in advance, Justin Dowswell (he/him) Technology Coordinator Tenants' Union of NSW 02 8117 3721 tenants.org.au

by BRANNON, CHRISTOPHER 23 Apr '26

23 Apr '26

Dost thou possess a trove of unruly patron data, wild and ungoverned? At times, the Batch Patron Modification tool may serve to tame such chaos. Yet oft, it proveth insufficient to the task, and something more is required. In such hours, the art of exporting and importing patron records, that they may be wrought upon by external means, doth offer welcome aid. This week, good George shall guide us, step by step, through the humble craft of exporting, shaping, and restoring patron information to its proper form. https://youtu.be/4tDRi-jy5jk Respectfully, Christopher Brannon koha-US Admin

Mailing list upgrade
by Paul Poulain 20 Apr '26

20 Apr '26

Hello Koha users, We have moved the koha mailing list to a new platform, and are now about to upgrade from mailman v2 to mailman v3. Nothing will change for you, BUT there will be a migration delay (a couple of hours) where emails won't be distributed, so don't worry if any email to the list seems to be lost: it will be distributed once the upgrade is done. -- Paul Poulain, Associé-gérant / CEO BibLibre, Services et logiciels libres pour votre bibliothèque BibLibre, Open Source software and services for your library
