  • Article

 

Applies to: SharePoint Server 2010 Enterprise

Alert Name:   Visio application proxy has invalid endpoint

Event ID:   8049

Summary:   The application for Visio Services in Microsoft SharePoint Server 2010 uses a proxy to abstract communication between the front-end service and back-end service. This proxy also provides a load-balancing mechanism between servers. For Visio Services to function, the front-end service must be connected to the application server that is returned by the application proxy.

Symptoms:   One or more of the following symptoms might appear:

  • Visio Services in SharePoint might fail to render diagrams.

  • This event appears in the event log: Event ID: 8049 Description: Application proxy invalid endpoint for <descriptive text>.

Cause:   One or more of the following might be the cause:

  • The specified SharePoint Server application server is inaccessible.

  • The specified application server is responding slowly due to heavy network activity or load on the specific server.

Resolution:   Check the error logs

  1. Open the Windows Event Viewer.

  2. Search for event ID 8049 in the Windows Application Event log.

  3. In the event description, note the application server that is failing.

Resolution:   Verify the application server connection

  1. From the failing application server, open the SharePoint Central Administration Web site.

  2. If you cannot access the Central Administration site from the failing server, check that the network settings are correct and that the server has appropriate permissions to join the SharePoint farm.

Resolution:   Verify that Visio Services runs on the failing server

  1. On the Central Administration page, in the reading pane, in the System Settings section, click Manage servers in this farm.

  2. Verify that Visio Services runs on the failing application server.

Resolution:   Restart Visio Services

  1. On the Central Administration page, in the reading pane, in the System Settings section, click Manage servers in this farm.

  2. In the Server column, click the name of the failing application server. The Services on Server page opens.

  3. In the Service column, locate Visio Graphics Service, click Stop, and then click Start.

Resolution:   Create a new Visio Services application

  1. On the Central Administration page, in the reading pane, in the Application Management section, click Manage service applications.

  2. In the Type column, click the name of the Visio Services application that has the failing service instance.

  3. On the ribbon, click Delete.
