XADM: JET Will Now Retry 16 Times on -1018 Error

• Microsoft Exchange Server, version 5.5

SYMPTOMS

The JET error -1018 (JET_errReadVerifyFailure) appears in the Windows NT Event Viewer application log during normal operation of the Information Store or Directory service. Also, the error -1018 is returned during the online backup procedure of the Information Store or Directory service.

CAUSE

A -1018 error occurs when the Exchange database engine makes a request to the operating system or hardware to return page X from the database on disk; but the operating system or hardware returns page Y. This can result from many things such as faulty hardware, SCSI timing problems, and so on. For a detailed explanation of -1018 errors please see the following article in the Microsoft Knowledge Base:

Q151789 XADM: Error -1018 (JET_errReadVerifyFailure)

STATUS

Microsoft recognizes the need for the Exchange database engine to retry when -1018 errors are encountered. We have modified Microsoft Exchange Server 5.5 so that the Exchange database engine will retry a maximum of 16 times when a -1018 error is encountered, logging an event in the application log for each retry.

To obtain this feature, obtain the latest service pack for Exchange Server version 5.5. For more information, please see the following article in the Microsoft Knowledge Base:
