The Koha wiki gives some hints on tuning Koha at https://wiki.koha-community.org/wiki/Koha_Tuning_Guide Adopting the suggested changes for MySQL/MariaDB effectively killed my database server due to `Thread stack overrun`s. Searching around the culprit was identified: ``` thread_stack = 128K ``` To avoid that others to hit the same issue, I commented this line in the Wiki and added a comment on the issue. However, the issue hints that this page could use some rework by experts in the field.
