I can answer myself: it turns out proxysql was introduced not so long ago. There's an option in globals.yml to enable/disable it and after disabling kolla-ansible skips starting proxysql and continues with haproxy. So this case can be closed. I'm not sure if this is even possible, but it would be great if proxysql could dynamically adjust to the actual system page size.

I have posted the bug here including more detailed description: https://bugs.launchpad.net/kolla-ansible/+bug/2117309 . What is interesting, version 2023.1 works just fine on the same HW/OS platform. I would be grateful for any suggestions on how to resolve this. Best, Dariusz Bursztynowski
