Perhaps the database was restarted and the app lost connection? It
*should* reconnect, but perhaps there is a bug with mySQL? Try restarting
the apps. If that does not work, then someone has changed something on the
machine (paths, permissions, passwords, deleted something etc.). Find out
what happened and fix it.
