One of our Drupal servers lost connection to where our ubercart files are located (see below)
and then within all of our users "File downloads" section (https://domanname/user/21/purchased-files) it lost all of their listing of purchased files and also all the ubercart products lost their association to attached Feature/File download files. It appears that shortly after a Drupal server loses connection to where the ubercart files are located it then deletes all the associations to ubercart Feature/File download files and also all the users "File downloads" sections are empty.
How do I prevent this from happening when one of the drupal servers has lost the connection to the product files directory?
