title: database configuration does not specify adapter
body: <p>I'm getting this error when I'm trying to connect to a mysql database. The problem is that the application works for weeks, and then randomly I get this message. When I get this error message the application is not able to reconnect to the database until I restart it.</p>
  
  <p>I'm using a configuration file to connect to the database, and the adapter is specified...the database configuration is not generated at runtime.</p>
  
  <p>Do you have any idea on what is going on?</p>
