    Question Unanswered: Ora-07445

    I got these errors:
    Errors in file /bdump/bogar_p002_17426.trc:
    Ora-07445 Exception encountered: Core Dump [ ] [SigSegs][ Address not mapped to object][3590324768][ ][ ]

    Errors in file /bdump/bogar_pmon_23178.trc:
    Ora-07445 Exception encountered: Core Dump [ ] [SigSegs][ Address not mapped to object][4][ ][ ]

    Errors in file /bdump/bogar_snp0_23196.trc:
    Ora-00603:Oracle server session terminated by fatal error
    ORA-00449: background process 'LGWR' unexpectedly terminated with error 1092
    ORA-01092:Oracle instance terminated. Disconnection forced.
    in the alert log.

    Does anyone know what cause the problem? How to prevent it?

    TIA.

    This is an indication of an OS Core Dump ... Not a pretty picture ...
    You should call Support, or at least go to Metalink and lookup the error
    and parameters that the error gave you in [] ...

    In addition to the above, there should be a stack trace in the trace file too which can be useful when searching metalink.
