I didn't run your application, but it doesn't matter.  As I pointed out 
the primary problem you have is that your application processes are not 
running as root.  If you don't fix that, you can't expect your 
application to work.  I confirmed that you can run Hydra as root 
correctly.  Till you get to that stage, I don't think we can do anything 
to help you.

Well, all I can do is discourage you from using it.  It's finally your 
call.  But we can't spend more time debugging this for you unless you 
follow our recommendations.
