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.
