    You can check for what session is blocking the redo thread with the following - depending on what is blocking, sometimes you need to kill the session that is blocking:

    SELECT 
    session_id, 
    command, 
    blocking_session_id, 
    wait_type, 
    wait_resource,
    wait_time   
    FROM sys.dm_exec_requests 
    WHERE command = 'DB STARTUP'
