WebEx Codec Plus looses Audio randomly during a WebEx CMR meeting

Software version:ce 9.5.0 fb56c25334b 2018-09-13

Registration: On-prem Expressway Core Cluster

One of our codecs randomly looses audio for remote webex attendees for a minute while being connected to a WebEx Meeting using "Call My Video System". This happened again today twice during the same WebEx meeting. I am sharing the logged events from the codec when this issue happened. I am not sure what these log entries on the event log indicate. But wanted to know experts opinion that is this something which could be responsible for audio drops during the webex meeting.

Now that I looked deeper, I see it on all the codec happening at the same time. This cannot be a coincidence. See two other examples below:
