What do they mean and how do I fix them?

Additionaly, I tried running the Intermediate VIsion example and when I changed the camera properties to the OpenCV output I got the following error:
ERROR: serve_Processed: : Too many simultaneous client streams (MjpegServerImpl.cpp:403)

What do these errors mean and how do I fix them?

Thanks in advance!
Well, I fixed the problem that the template did not work, but the CvSource keeps sending the error that it has no connection, why does this happen?
