Exchange 2010 - Event ID 118&510 RRS feed

  • Question

  • Hi

    I am hoping someone can help me with the below issue I am having on Exchange 2010.

    Every day at 6pm I am getting Event IDs 118 & 510, we have staff who work at 6pm plus and they are experiencing severe performance issues and disconnections around these times.

    There are TWO Exchange 2010 servers in a Clustered environment running on a Windows Server 2008 R2 Enterprise, each server has 6.00GB RAM and has a Intel Xeon 3.10 Ghz processor and is running in a Virtual Environment on Hyper-V.

    Please find the below Events:

    Log Name:      Application
    Source:        ExchangeStoreDB
    Date:          01/10/2012 18:09:31
    Event ID:      118
    Task Category: Database recovery
    Level:         Error
    Keywords:      Classic
    User:          N/A
    Computer:      XXXXXX.XXXXXXX.local
    At '01/10/2012 18:09:29' the copy of database 'XXXXXXX' on this server appears to be experiencing performance issues, possibly as a result of storage failure. Consult the event log on the server for other storage and "ExchangeStoreDb" events for more specific information about the failure. Recovery was not attempted.

    We have already increased the memory, rebooted the server, checked the status of the Databases (they don't appear to be corrupt).

    If you require any further info then please don't hesitate to ask and any help provide would be greatly appreciated, this has been a long outstanding issue and needs resolving.

    Many Thanks

  • Hi,

    This does sound as if you have a storage issue.

    Is the Exchange storage SAN based?

    If yes what else is using the same SAN (and doing something special at that time)?

    Are you running backup at 6 pm ?

  • Hi Leif

    Thanks for replying so quick.

    Running in a Hyper-V environment the servers are all running with external storage with other VM servers running on it, but the Exchange DBs are running on a virtual hard disk rather than directly on the SAN......hope that makes sense.

    The SAN has already been checked and isn't running any tasks around that time.

    Many Thanks

  • Hello,

    For event id 510, this problem may be caused by faulty hardware. This problem may also be caused if the server or disk subsystem is not correctly configuration.

    There are few information on the event id 510. I search an article on the description for event id 510 for your reference.

    Event 507

    Have you used Performance Troubleshooter in the Toolbox to seek the performance related issue?

  • Hi Cara

    Thanks for the response.

    We have decided to build a new VM with a new DB and migrate the users to that server. Thanks for your help.
