Description

Apparently the script mysqld_multi assumes the configuration of an instance is in a single file. But when you're using different snippets under conf.d/ the function find_groups() matches the same instance multiple times, leading to the concurrent run of the same instance with the risk to crash database.
Patch is in attachment, it's trivial and can save a lot of trouble.
