Recently the root file system on this machine has started filling up rapidly (in as little as a few minutes). The file /var/log/syslog grows in size to more than 40 Gbyte before filling the file system. Logrotate is working, but can not prevent the root filesystem from filling to 100%.
The following is a snippet from the end of the Syslog file:

The above command is repeated continuously for about the last 39 GByte of the syslog file, so there are potentially millions of entries with the same error.
According to the above errors, the Process ID causing the errors is [1443], which is reported as follows:
royg 1443 1198 0 Jan26 ? 00:00:00 /usr/lib/gnome-session/gnome-session-binary --session=ubuntu
Apart from the root file system filling up, there are no other symptoms. The computer does not freeze, or anything else. The system is used as a media server with Kodi, TVHeadend, and Transmission as the three main User applications that are running all the time.
Can anyone advise what is causing this problem, and how I can rectify the problem.
Many thanks,
Roy Gilby
