How to remove previous unix domain socket while closing RTCpeerconnection in webrtc in nodejs

Question

const { RTCPeerConnection } = require('wrtc')


this.peerConnection =  new RTCPeerConnection(this.rtcConfig)

------------- some coding --------------------------------------------------

this.peerConnection.close();
    

//In above code i am closing the peerConnection but still previous unix domain socket continue to //exist and not getting destroyed and its increasing whenever i create new peer connection- below are //the logs of my process checked in terminal

unix  3      [ ]         STREAM     CONNECTED     3410597  14738/Liveview

i am expecting that when we close the rtcpeerconnection the unix domain socket related to that peer connection should be cleared
