Please check that the module has indeed fails to load.

Asterisk's module loader has no information about module dependency, and
thus just tries loading modules in a loop, and keeps retrying. The
problem is that it emits those error messages each time it fails and not
just when it gives up.

And yes, this is a bug on its own.
