XADM: Event ID 116, Service Database Corruption (190696)

The information in this article applies to:

Microsoft Exchange Server 4.0
Microsoft Exchange Server 5.0
Microsoft Exchange Server 5.5

This article was previously published under Q190696

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, "Source" above is "EDB".

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.
