XADM: ESE Will not Retry Operations during ESEUTIL /G

• Microsoft Exchange Server, version 5.5

SUMMARY

When the Exchange Database Engine encounters a read verification failure, referred to as an -1018 error, (in accordance with Knowledge Base article Q151789, XADM: Error -1018 (JET_errReadVerifyFailure)), it will now retry to successfully read the page a maximum of 16 times. This is a new feature of the Exchange Database Engine, referred to as "ESE," and was introduced in build 5.5.2395.0 of Ese.dll.

However, when using ESEUTIL to perform an Integrity Check (ESEUTIL /G), retry operations are not performed if the Exchange Database Engine encounters a read verification failure. If ESE retries to read the page it originally failed on (when running either Repair or Integrity Check), the length of time to run ESEUTIL increases dramatically.

MORE INFORMATION

Retry operations will occur when running ESEUTIL in either Repair (/P) or Integrity Check (/G) modes using a build of Ese.dll between 5.5.2395.0 and (but not including) 5.5.2416.0.

However, because Ese.dll build 5.5.2416.0 retry operations are not performed if the Exchange Database Engine encounters a read verification failure during ESEUTIL in either Repair (/P) or Integrity Check (/G) modes, this version of Ese.dll is included with Microsoft Exchange Server 5.5 Service Pack 2.
