From bedc003fb209930a8021cb0aca88c1379c750887 Mon Sep 17 00:00:00 2001 From: Dmitriy Rabotyagov Date: Sat, 25 May 2024 15:21:01 +0200 Subject: [PATCH] Define unique hostname for QManager Due to the shortcoming of QManager implementation [1], in case of uWSGI usage on metal hosts, the flow ends up with having the same hostname/processname set, making services to fight over same file under SHM. In order to avoid this, we prepend the hostname with a service_name. We can not change processname instead, since it will lead to the fight between different processes of the same service.
