XADM: Event ID 116, Service Database Corruption

ID: Q190696

The information in this article applies to:

Microsoft Exchange Server, versions 4.0, 5.0, 5.5

SYMPTOMS

When you try to start the information store, the following Event ID appears the Windows NT event viewer application log:


   Event ID 116
   Source ESE97
   Type Error
   Category Database Page Cache

   MSExchangeIS ((52) ) Synchronous read page checksum error -1018
   ((1:1057816 1:3688618971) (3688618971-3688618971) (0-16815256))
   occurred. Please restore the databases from a previous backup.

NOTE: For versions 4.0 and 5.0, [ASCII 147]Source[ASCII 148] above is [ASCII 147]EDB[ASCII 148].

CAUSE

The Microsoft Exchange Server computer has suffered from service database corruption as a result of the Exchange database being compressed and growing beyond 4 GB in size.

WORKAROUND

To work around this problem, decompress the database drive, if applicable, and restore from a backup.

If a good backup is not available, decompress the Priv.edb and Pub.edb files and bring the database to consistency by performing an EDButil /r /ispriv and/or /ispub for Exchange Server versions 4.0 and 5.0. For Exchange Server version 5.5, use ESEutil /r /ispriv and/or /ispub.

If the above steps are not successful, the database may need to be repaired to bring it to consistency.

MORE INFORMATION

Database compression is only one possible cause of -1018 errors.

You may encounter the -1018 errors at any time, not just at startup.

You may also get an asynchronous read page error with a different Event ID. Both are -1018 errors, however.
