Hello,
The filereader is restarting because it can't load any policies from the database. We see:

INFO: Waiting for policies...

This shows that we are waiting 16 minutes and then restarting Filereader due to no communication. This is how DLP is designed. You should check the MonitorController logs on Enforce. If you can restart the MonitorController Service, that might clear things up. Otherwise, you will need to check an make sure that the Enforce Server can communicate with the Detection Server on port 8100. That's how the policies get sent to the server and then they are loaded in to Filereader.
Reply back if the issues persist, or open a support case.
Best,
Ryan
