This also causes a rather large memory leak every time this orphaned stream occurs.

Our software is successfully listening and receiving however closing the incoming stream before sending the command to remove the stream causes this to occur as well.

We have been forced to send the AMCP command to remove the stream and rely on ccg to close the stream itself.
