Tracking file filling syslog file with errors

thanks for what you are doing here. I have used the forum all the time to fix problems on my ubuntu 20.04 LTS installation.

This installation is my first, so apologies if I am missing something obvious to you guys.

I am getting a repeated error which is causing my syslog to fill quickly. I don't notice any functionality changes in my machine, other than the syslog filling quite fast, but I haven't done anything strenuous with it in a while. The syslog will fill until the drive is full, and then I have to start in recovery mode and remove the log file before I can get onto my desktop.

The log and some reports before it starts repeating:

If I kill the process tracker-extract from system monitor or terminal with kill -9 1826, the syslog file continues to fill up.

How can I find and destroy whatever is causing this problem? I installed a good amount of stuff before I realized this was a problem.

Thanks in advance
