Volley.NoConnectionError: java.io.EOFException 0

I don't understand this error, although I am on the net many times, but doing nothing, the error appears somewhere. I made an application that uses the VOlley library and everything works well, 95% of my request works, but someday I have an error;

11-12 12:18:54.991: I/Error(1870): com.android.volley.NoConnectionError: java.io.EOFException 0

      

        
        
        
      

    

and I don't know why this error appears. Example during y COnnection to app, I send somes information like register_id to receive GCM notification, login, password and imei, and sometime I have this error that appears 0_0

This is my login request (but in my entire request that I have this error):
