MSExchangeIS Mailbox Store 1097 Background Cleanup Error RRS feed

  • Question

  • I got that error on Exchange 2007 SP3 server. One error message, not during regular maintenance window. 

    Event Type:    Error
    Event Source:    MSExchangeIS Mailbox Store
    Event Category:    Background Cleanup
    Event ID:    1097
    Date:        11/29/2011
    Time:        5:45:00 PM
    User:        N/A
    Computer:    MBX1
    Description:
    Error 0x8004010f occurred while cleaning up background folder 5-9C8BFC000A on database "sg_2\db_2".

    I found a couple of articles that say it's safe to ignore, but I also found this article:

    Thoughts?

  • Exchange store maintenance is the term applied to a series of operations performed by the Microsoft Exchange Information Store service to ensure logical consistency in the databases.
    The operations ensure items no longer needed by the system are removed from the database.
    If a custom schedule has not been defined for the database in Exchange System Manager, a default scheduled period from 00:00 through 05:00 local time will be used.

    Overall, there are 10 tasks performed by the Microsoft Exchange Information Store service during this period.

    If the maintenance window ends before one of the 10 tasks is completed, the last task running is recorded. The last task will be allowed to run until completion, which could exceed the maintenance window. During the next maintenance window, the Microsoft Exchange Information Store service determines the last task in progress and restarts the process, essentially picking up where it left off on the next task.

    An eleventh task, online defragmentation, is performed by Extensible Storage Engine (ESE). At the completion of the list of tasks, the Microsoft Exchange Information Store service initiates online defragmentation by calling ESE to start the defragmentation process. This process will start only after at least one of the 10 tasks has been successfully completed

    This is the reason why we got the event 1097 even after the Online maintenance schedule.


    If at least one of the maintenance tasks was able to complete within the maintenance schedule, the Microsoft Exchange Information Store service requests that ESE begin an online defragmentation cycle. This process will run for at least 15 minutes at the end of the maintenance window. It is important to note that the online defragmentation process will suspend itself if a backup starts for any database in the storage group.

    If a pass of the online defragmentation was interrupted due to window expired or backup initiated, the 1097 event is logged.

    This event can be safely ignored.

    Resolution:
    ===========

    Increase the online maintenance interval and make sure that backup job is not initiating within maintenance window.
