class DbRunRecoveryException : public DbException { ... }; 
      
            This information describes the DbRunRecoveryException class and how 
            it is used by the various Berkeley DB classes.
    
        Errors can occur in the Berkeley DB library where the only solution is to shut down the
        application and run recovery (for example, if Berkeley DB is unable to allocate heap
        memory). When a fatal error occurs in Berkeley DB, methods will throw a
        DbRunRecoveryException, at which point all subsequent Berkeley 
        DB calls will also fail in the same way. When this occurs, recovery should be performed.
    
        The DbException errno value is set to
        DB_RUNRECOVERY.
