By default, udm_manager starts out with loglevel 1.
When set to this log level it does not retain logs and causes a problem.
When logging is increased to loglevel 5 it generates a LOT of transactional

Using Raw configure, CTRL+ right click, on the udm_manager you can reduce the loglevel.
Once this is done, deactivate the probe and then remove the log files from:
Then activate the probe again and the issue should be resolved.
