I am encountering the same issue in 20.04. The message is repeating approximately every three seconds, resulting in log files of hundreds of gigabytes. It also makes the system log nearly useless for any other use; it is near-impossible to even open the file, and causes logrotate to hang up for hours every time it attempts to run since it attempts compression.
