Business Data Connectivity Service - BDC Proxy - unexpected exception - Event 8085 (SharePoint 2010 Products)
Published: May 12, 2010
Alert Name: Business Data Connectivity Service - BDC proxy unexpected exception
Event ID: 8085
Summary: When a Web server receives a request from a client computer, it routes the request to an application server through a load balancer. The load balancer maintains a list of available servers for a given service application. If the Business Data Connectivity service application on one or more application servers does not respond, the load balancer drops the application server from the list of available servers and this event is logged.
If the Business Data Connectivity service application is enabled on more than one application server, the client computers may not be affected. If the service application is enabled on only one application server, the client computers that rely on the metadata in the Business Data Connectivity metadata store will fail to read or write data from the external data sources defined in the metadata. The load balancer will ping the service application periodically and will automatically re-enlist it when it responds.
Symptoms: The client computers fail to read or write data from the external data sources.
Cause: One or the more of the following might be the cause:
The application server is not accessible or the Business Data Connectivity service application model does not have the correct connection properties for the external data source.
The external data source is currently not functioning and is not responding.
