Description

The ModuleManager::load() is designed to be called exactly once during a process lifetime. This works well for Master/Agent environments. However, it can fail in Scheduler environments. For example, a single Scheduler binary might implement multiple scheduler drivers causing multiple calls to ModuleManager::load() leading to a failure.
