Misc
If the 'Fetch messages from queue'-PHP script is placeced in cron,
you should implement some file-locking logic
to prevent concurrent processes running.
Ex: https://www.php.net/manual/en/function.flock.php#117162
You should always set the 'RETURNCHUNKSIZE' config key
otherwise the 'Fetch messages from queue'-PHP script may
continue forever i.e. until PHP exec script timeout.
Using more complex class instances (with ex Closure) as message
may throw a serialize Exception.
