automatic restarting-reg

Sir,
    We are running Oracle9I Database on linux2.1As. Some times the Server is rebooting automatically during night time even though there is no load on the system.

    After Opening the dmesg file, i found an error "MP table in the EBDA can be UNSAFE". kindly give  some information in this regard and solution for the problem.

               Thanking you sir,

                               MRV Sastry
                               BSNL-Eluru.
