Event ID: 1104

Symbolic Name: UsingDefaultValueForRetireTime
Message: The Unified Messaging Service was unable to read the UM worker process retire time from the configuration data. The UM worker process retire time is being set to the default value, which is “%1”. Reason: “%2”
   
Explanation

This Warning event indicates that the retire time of a worker process is set to the default value of 30 minutes. The retire time is the maximum duration that a worker process will stay active before stopping. If the maximum duration is exceeded and the worker process has not been shut down, the worker process will be stop automatically. Under ordinary conditions, the retire time is based on the maximum call duration defined in the Unified Messaging (UM) dial plans associated with the UM server that generated this event. This event may be caused in the following conditions:

  • If one or more of the UM dial plans that are linked in the UM server configuration do not exist in the Active Directory® directory service.

  • If the UM server cannot retrieve complete dial plan configuration information from Active Directory.

   
User Action

To resolve this error, do one or more of the following:

  • Make sure that all UM dial plans that are linked in the UM server configuration exist in Active Directory. Dial plans are located in the following location in Active Directory: CN=UM DialPlan Container,CN=<Exchange Organization Name>,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=<Domain name>,DC=com.

  • Make sure no network connectivity issues exist between the UM server and the Active Directory domain controllers. For more information, see Microsoft Knowledge Base article 325487, How to troubleshoot network connectivity problems.
