I have issue with kurento media service. Sometimes it's broken with next warnings and error(unfortunately kurento logs without timestamps):
1st issue : I have a lot of next warnings:
(kurento-media-server:17737): WARNING **: Error sending data on stream 1: (104) Connection reset by peer
2nd issue:
** (kurento-media-server:7829): WARNING **: SCTP event SCTP_COMM_LOST received
I tnink it's network issues but I don't know something...
3th issue:
(kurento-media-server:7829): libnice-WARNING **: (agent.c:2156):agent_signal_component_state_change: runtime check failed: (TRANSITION (DISCONNECTED, FAILED) || TRANSITION (GATHERING, FAILED) || TRANSITION (CONNECTING, FAILED) || TRANSITION (CONNECTED, FAILED) || TRANSITION (READY, FAILED) || TRANSITION (DISCONNECTED, GATHERING) || TRANSITION (GATHERING, CONNECTING) || TRANSITION (CONNECTING, CONNECTED) || TRANSITION (CONNECTED, READY) || TRANSITION (READY, CONNECTED) || TRANSITION (FAILED, CONNECTING) || TRANSITION (DISCONNECTED, CONNECTING)|| TRANSITION (CONNECTING, GATHERING))
Some guys from StackOverflow said, it's not a problem
4th issue:

Your 1st issue means:- There is some network fluctuation ,try application in 4G network you will not receive a warning. You can ignore these warning ,but you should handle the onIceCandidate responses.
Your 2nd Issue:- Again your 2nd issue is related to network , but this time its in KMS end. KMS not able to transfer some data packets thats why this warning comes.
Your 3rd Issue:- it's not a problem.Its just a warning when websocket flailed to get runtime issue status.
