Hello, I have a Dell EISA server box with a Adaptec AHA1740 controller that has been working well for some time now. Lately I get messages on the console "aha1740[xx]_mbxout wait!" ,the xx is a random number, but the system seems to be functioning properly. Is this something that I should be concerned about or just ignore and it will go away next time I update the system and get the new drivers. John Ellingboe
