What authenticator and/or installer plugin is used? The apache plugin requires reloads for the authentication and/or installation tasks. Unfortunately, all the certificates use a “separate” instance of the plugin, so every cert will separately reload twice (or even thrice).
Using a hook will not tell the apache plugin not to reload. The reloading is required and the plugin doesn’t “pool” all the authentications or certs to minimise the reloading.
Why is reloading even an issue if I may ask?
