Warning: Sending large locally-generated RTCP packet of size 15436

A user of my self hosted Jitsi instance reported multiple disconnects during a two hour video conference. I don’t have any error logs from his browser console, but the times of the disconnects, so i checked /var/log/jitsi/jvb.log. Before every disconnect I found the following Warning repeated for about 10 times:

I dont really have an idea what these warnings could mean. Can anyone help with that?
Could they be related to a user disconnecting?

Thanks!
