Η ομάδα του Exchange στο χθεσινό blog post 29 Μαρτίου 2011 , αναφέρει μερικά περιστατικά σε πελάτες με Exchange 2007 Service Pack 3 με Update Rollup 3 (Exchange 2007 SP3 RU3), για πιθανό database corruption.

Εάν παρατηρήσετε ότι λαμβάνετε μηνύματα λάθους στο Event Viewer σαν τα ακόλουθα και έχετε εγκατεστημένο το RU3 στον Exchange 2007, επικοινωνήστε με το Microsoft Support για υποστήριξη.

  • Event ID: 454
    Event Type: Error
    Event Source: ESE
    Event Category: Logging/Recovery
    Description: Microsoft.Exchange.Cluster.ReplayService (12716) Recovery E20 SG1\DB1: Database recovery/restore failed with unexpected error -4001.
  • Event ID: 2095
    Event Type: Error
    Event Source: MSExchangeRepl
    Event Category: Service
    Description: Log file D:\logs\SG1\E200006AFAE.log in SG1\DB1 could not be replayed. Re-seeding the passive node is now required. Use the Update-StorageGroupCopy cmdlet in the Exchange Management Shell to perform a re-seed operation
  • Event ID: 2097
    Event Type: Error
    Event Source: MSExchangeRepl
    Event Category: Service
    Description: The Microsoft Exchange Replication Service encountered an unexpected Extensible Storage Engine (ESE) exception in storage group 'SG1\DB1'. The ESE exception is a read was issued to a location beyond EOF (writes will expand the file) (-4001) ().

This issue is of specific concern in two scenarios: 1) when transaction log replay is performed by the Replication Service as part of ensuring the passive database copy is up-to-date and/or 2) when a database is not cleanly shut down and recovery occurs.

While only a small number of customers have been affected to date, we believe the risk is significant enough that we are recommending all customers to uninstall Exchange 2007 SP3 RU3 on all Mailbox Servers and Transport servers. Uninstalling the rollup will revert the system back to the previously installed version. We have also removed the Exchange 2007 SP3 RU3 download from the Microsoft Download Center and from Microsoft Update until we are able to produce a new version of the rollup.
