Transport service is disconnecting performance counters with process lifetime from their old process.


This Warning event indicates that the Microsoft Exchange Transport service is resetting transport-related performance counters.

Microsoft Exchange Server 2010 uses an ESE database to store messages for routing throughout an Exchange organization. On servers that run the Edge Transport role, the database queues those messages that are received from or are directed to the Internet. On servers that run the Hub Transport role, the database queues those messages that are transferred throughout the Exchange organization. Exchange 2010 includes the following transport queues:

  • Submission queue

  • Mailbox delivery queue

  • Remote delivery queue

  • Poison message queue

  • Unreachable queue

The Microsoft Exchange Transport service automatically creates these queues on an as-needed basis for temporary message storage.

When the Microsoft Exchange Transport service stops, Reliability and Performance Monitor may still track transport-related processes. Therefore, when the service starts, it disconnects the performance counters from old transport-related processes to start monitoring the newly-started processes. For more information about the transport architecture in Exchange 2010, see Transport Architecture.

User Action

No user action is required. However, you may want to investigate the issue further to determine whether restarting the Microsoft Exchange Transport service was intentional. To do this, do one or more of the following:

  • Revise si hay eventos relacionados en los registros de la aplicación y del sistema en sus servidores Exchange 2010. Por ejemplo, puede que los eventos que tienen lugar inmediatamente antes y después de este evento aporten más información acerca de la causa original de este error.

  • Review the Operations Console in Operations Manager for detailed information about the cause of this problem. For more information, see the "Introduction" section in this article.

  • You may want to increase diagnostics logging to log the component startup sequence during the startup process of the Microsoft Exchange Transport service. To increase diagnostics logging for the Transport component, follow these steps:

    1. In Registry Editor, locate the following registry subkey:

      HKEY_LOCAL_MACHINE\SYSTEM\Current Control set\Services\MSExchangeTransport\diagnostics

    2. Set the following REG_DWORD values to 7:

    • Smtpreceive

    • Smtpsend

    • DSN

    • Components

    • Remote Delivery

    • Categorizer

  • Examine the Application log to determine whether any other logged events indicate that message processing has experienced a problem.
