It sounds like you don't have max_trace_level high enough. Check out 
global settings and max_trace_level in the manual, it basically tells 
POV how many levels it can go into the scene, too few will cause 
disappearing reflections and dark areas. If this is the problem, it 
won't disappear no matter how many light sources you use.
Try adding this to the beginning of the scene:
global_settings {
    max_trace_level 24// 7 is the default, this often needs to be
                      // increased in scenes with reflection or
                      // transparent objects
}

It is not required in the current version, but might be in a future 
version. You had better get in the habit now, while the only problem it 
causes is a warning.(if it happens in a loop, all those warnings can 
also slow parsing down)
