Microsoft® Exchange Server 2003 Service Pack 1 (SP1) introduced a new error-correcting code (ECC) algorithm to help resolve -1018 errors that may occur in an Exchange Server database. ESE event 399 indicates that a single-bit error has been detected, and that this error has been successfully corrected in memory. In this scenario, the page where this error occurred may have been corrected on the physical hard disk. The single-bit error is not corrected on the physical hard disk unless the page has been written to. Therefore, if the database page is only read, the single-bit error is corrected in memory, but the single-bit error is not corrected on the physical hard disk.
For information about the error-correcting code (ECC) algorithm introduced in Exchange Server 2003 Service Pack 1 (SP1), see 867626, New error correcting code is included in Exchange Server 2003 SP1.
To resolve this event, do one or more of the following:
