System.ServiceModel.Channels.ConnectionPoolCloseException
An exception occurred while closing the connections in this connection pool.
Description
This error level trace indicates that an error has occurred while closing the connection pools used by Windows Communication Foundation (WCF)’s connection pooling feature. One possible reason for this is an unsuccessful closure of a pooled connection, or a set of pooled connections within the CloseTimeout. When this exception is thrown, any remaining unclosed connections within that pool are aborted; unclosed connections within other pools are abandoned.
