Too many kurento-media connections

System: centos7.4
openvidu version: 2.16.0
There are N terminals in a conference. After the terminal publishes Video for the first time, by executing “netstat -anp | grep ‘kurento-media’ | wc -l” , the above statistical results will increase by 8N.

Question: What are these added connections? Will they have any impact?

Any suggestions or comments would be greatly appreciated!
